Hello,
I've been working through Patrick Michaud's excellent videos from the
The Perl Conference 2016. At about 35:45 of the following 2016 video
(Part 1 of 2), Patrick discusses arrays:

At this point in the video, Patrick also discusses push() and
Thank you Yary. It's not often I have to prepend a "4" to a mixed list
items of containing numbers, but your code is perfect for extracting
the numbers and prepending a dollar sign ($):
> .say for (325, '44a', 555, 6).grep(/^\d+$/).map( '$' ~ * )
$325
$555
$6

Hi Richard, I'm not able to come to the same conclusions.
Specifically, the previous code examples starting with 'for lines()'
always have to have parentheses following 'lines' (as in 'lines()
{...}'), otherwise Perl_6 balks (examples 6 and 7 previously posted).
This is whether 'information is

Hi Wesley,

Hi Yary and Paul and Simon,

Hi Gianni,
Thank you for demonstrating use of the "Test" module in your code.
Just a short note that Eirik's array-based code seems to work fine,
with-or-without backslash-escaping the first input string (minimal
testing, below):
sub contains( Str $chars, Str $_ ) {
my @arr = $chars.comb;

Nil
> say 'abc' ~~ / @( $commasep.split(',') )
Someone might get a kick out of this ;-). Clearly regexes are built on
top of set theory, but as both Simon and Yary pointed out, my
set-based code didn't return the matching string "8420" present in the
target.
Example A, Eirik's code used an array to generate a character class,
and then tested
I'm wrong then. Nowhere on that reference page does the character
construction "<{...}>" (block wrapped in angle brackets) appear.
Per your reference, "pointy-blocks" seems to refer to an arrow in
conjunction with a block, as mentioned three times on the
'Python-to-Perl6' page:
Thanks Simon, good point. I ran into the same trouble as others trying
to get the answer via regex, and switched over to sets as an
alternative. I'll confess I completely missed that Yary's Perl5 code
returned the substring "8420" present in his test "19584203" string,
and that was the answer he

Hi Yary,
I went over this with Joe as well, and I was equally confused. So if I
understand what you're saying correctly, if we see something like
"Bool :$match" that says we should drop the dollar-sign ($) and enter

I can confirm what Yary is seeing with respect to the "lines(:!chomp)"
call. Below I can print things out on a single line (using "print"),
but the use of "print" or "put" appears to be controlling, not
manipulating the "chomp" option of "lines()".

Hi Joe,
Just a quick note to say that "Learning Perl 6" by brian d foy has a
section on reading binary files (pp.155-157). Check out the "Buf"

".read" takes an argument specifying how many octets you want to read
in.

This code below seems to accurately return the number of "repeating
digits" (576) using Perl6 alone:
mbook: homedir$ perl6 -e 'say
ly an
empty line or '0' ".

Hi Yary (and Todd),
Thank you both for your responses. Yary, the problem seems to be with
"get". I can change 'while' to 'for' below, but using 'get' raku/perl6
actually returns fewer lines with "for" than it did with "while":
[1]mydir$ cat testthis_abc_def.txt
a
b
c
d
e
f
[2]mydir$ perl6 -e
Hi Joe, I tested the code you put up using the REPL, and I have to
start off by saying that I was unable to reproduce your results,
specifically where you creat the "@m" array. This could be a
REPL-specific issue, or a version-specific issue (mine is 2019.07.1
Perl 6.d):
mbook:~ homedir$ perl6

Hi Timo and thank you for the note.
Yes, since I was working in the REPL, I tried compacting Joe's code by
eliminating the "my %stash" line at the top, and adding "my" to the third
line.
I figured since Joe's code looked like a closure (curly brackets and all),
it wouldn't be an issue.
But the

On the contrary, this email list is the perfect place to put up

Todd, are you looking for a range smartmatch, or possibly the
".in-range" method (Rakudo-only, below)?

Value out of range. Is: 248, should be in -128..127

Agreed. Thank you Trey!
Trey (or anyone else in the know), when Perl6 was developed, was there
any consideration given to implementing pure "three-valued" (Kleene or
Priest) logical operators, similar to SQL and/or R ? Just curious.

Hello All,
I've been reviewing literature that discusses using raku/perl6 as a
replacement for common unix utilities. One important unix utility is
"cat". I looked at docs/blogs and found a recommendation to use "$*IN"
along with "slurp" (references at bottom). Using a seven-line test
file

Hi Joe,
I was able to run the code you posted and reproduced the exact same
result (Rakudo version 2020.02.1..1 built on MoarVM version
2020.02.1 implementing Raku 6.d). I tried playing with file encodings a bit
(e.g. UTF8-C8), but I didn't see any improvement.

Hi Todd,
Yes, ** stands for exponentiation. And exponentiation has higher
precedence than multiplication. See below (I dropped a few zeros to
help clarify):

Hello,
I'm interested in knowing the differences between the return values
when "say" is used compared to "put". My understanding is that "put"
returns Raku's internal representation of a value held by a variable,
while "say" is merely "put" with the .gist method called on it (a
"human readable",
Hello,
Can anyone answer why--in a one-liner using the "-pe" flag--the s///
and tr/// functions do not require a "." (dot) preceding the function
call? Clearly adding a "." (dot) before either one results in an error
(code below). Also, adding a ".=" (dot-equals) sign before the either
the s///
Thank you, Gianni (and Laurent). I really appreciate you both taking
the time to explain the intricacies of Raku/Perl6. Sincerely, Bill.
