in reply to Passing multiple arrays to foreach loop

The only situation in which you will get into trouble is if you include an honest-to-goodness list literal in your for-loop iteration list and then try to do some mutating operation on it.

>perl -wMstrict -le "my @ra1 = qw(foo bar); my @ra2 = qw(does not get here); ;; for my $file (@ra1, 'zonk', @ra2) { $file .= '-appendage'; print qq{'$file'}; } " 'foo-appendage' 'bar-appendage' Modification of a read-only value attempted at -e line 1.
