Perl::Critic::Policy::CodeLayout::RequireTrailingCommas
Conway suggests that all elements in a multi-line list should be separated by commas, including the last element. This makes it a little easier to re-order the list by cutting and pasting.
my @list = ($foo,
$bar,
$baz); #not ok
my @list = ($foo,
$bar,
$baz,); #ok
In the PPI parlance, a ``list'' is almost anything with parens. I've tried to make this Policy smart by targeting only ``lists'' that have at least one element and are being assigned to something. However, there may be some edge cases that I haven't covered. If you find one, send me a note.
