The :foo syntax is called a "colon pair", and colon pair also
describes :quux since it is short for :quux(True)
Colon pair also describes :$foo because it is a shorthand using a colon to

:nl-in is a named parameter that defines what the method lines would

Hi All,
Dumb question:
Does the "multi" in "multi method" mean there
is more than one way to address a method?
Or, are the all methods "multi methods".
If not and the method is a multi, should not the
documentation show all (more than one) the ways of
addressin

While the original documentation you were referring to called them Pod

So back to my original question, where are the "=end " for
the other blocks?
I am confused.

They're not Pod comments, they're Pod abbreviated blocks:

Hi All,
I am somewhat confused about pod comments:
https://docs.raku.org/language/syntax#Pod_comments
Seems pretty straight forward. But when I look at
https://github.com/tadzik/perl6-Config-INI/blob/master/lib/Config/INI.pm
starting line 45, I see
=begin pod

Is it (2 x 100)^ 2000
Or 2 x ( 100^ 2000 )2 times (100 to the 2000 power)?
Your point 1 only applies if it is an exponent. Is the
2000 an exponent? Does ** stand for exponent?

In this instance, I do not care about meaningful. I only
care about the noise. Just has to be repeatable.

Hi All,
1) how do I get 40 or more digits out of sqrt?
2) how to I assist those bytes to a 40 (or more)
byte long Buf?
This obviously does not work:
my Num $x = 3.sqrt; my Buf $y = Buf.new($x)
Type check failed in initializing element #0 to Buf; expected uint8 but
got Num
Hi Timo,
Thanks for the answer:

I didn't knew about this principle. I'm now going down the rabbit hole.
Is this always the case for all the derived classes in Raku?

The problem is that you are using ~ with an uninitialized Buf/Blob
my Buf $read;
$read ~ Buf.new;
# Use of uninitialized value element of type Buf in string context.
Note that it is not complaining about it being a Buf. It is complaining
about it being uninitialized.

Hi David,
"my Blob $read" will define the variable $read to 1) only accept things
