Since you may not be familiar with this type of assignment, I just wanted to clarify something about this line:
my ( $top_entry, @entries ) = @_;
The order of scalar vs array is really important. For example:
#!/usr/bin/env perl use strict; use warnings; use feature 'say'; my @original = qw(a b c d); my ( $first_item, @the_rest ) = @original; say "First item: $first_item"; say "The rest: @the_rest"; my ( @array_first_bad, $last_item ) = @original; say "Array first is bad: @array_first_bad"; say "Last item: $last_item"; __END__ First item: a The rest: b c d Array first is bad: a b c d Last item: Use of uninitialized value $last_item in concatenation (.) or string a +t line 16.
