A rather direct translation:
for lines() {
# .=chomp;
print join("\t", .split(':')[0, 2, 1, 5] ), "\n";
}
Note that for `.=chomp` to work, you probably have to declare `$_` as `is
copy`.
for ("a\n", "b\n") -> $_ is copy {
.=chomp;
print join("\t",
My guesses at Perl 6 versions of the Perl 5 example:
say .split(':')[0, 2, 1, 5].join("\t") for lines;
-or-
for lines { say .split(':')[0, 2, 1, 5].join("\t") }

Hello, Just a short backgrounder to say that this question arose this
past weekend at a Perl6 Meetup (Oakland, CA). Specifically we were
looking at how to write a Perl6 version of some introductory Perl5
code in "Learning Perl", 7th Edition by Tom Phoenix, brian d foy,
Randal L. Schwartz:
#Perl 5
Also, you can make this conditional: show me all the comment lines of a source
file:
$ perl6 -e '.say if .starts-with('#') for lines' source-file

Also no need for all the brackets
.say for lines;
This is quite idiomatic Perl 6 and not golfing

In Perl 6, you also don't need to explicitly use $_ in this case if
you use the method form of say.
for lines() {
.say
}

Exactly, I was just looking there, and I ended up playing around with
the method form of lines, and didn't think to try the function
form of it.
To summarize, if the goal is to write a
