Re^2: Assignments for Subroutines

$,=", "; #change list delimiter for fancy printing
print @evens;
print "\n"; #newline
$,=""; #change list delimiter back before it is a problem
[download]

That could be written as

{
local $,=", ";
print @evens;
print "\n"; #newline
}
[download]

No need to change it back, less possibility of an error. My 2 cents.

I'm too lazy to be proud of being impatient.

Indeed. Especially because this... `$,=""; #change list delimiter back before it is a problem` [download] ... changes the list delimited "back" to the empty string, when we never checked that it started off as the empty string to begin with! `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l]
