in thread Assignments for Subroutines

$,=", "; #change list delimiter for fancy printing print @evens; print "\n"; #newline $,=""; #change list delimiter back before it is a problem
That could be written as
{ local $,=", "; print @evens; print "\n"; #newline }
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

    ... changes the list delimited "back" to the empty string, when we never checked that it started off as the empty string to begin with!
