I have some things that come back to bite me ... a few are :
# getting just the year
$y = (localtime($utc))[5]+1900;
# Basic hash un-rolling
# (this is an example, better var names in real life)
foreach my $a (sort keys %hash) {
foreach my $b (sort keys %{ $hash{$a} }) {
# co-workers stumble at the line above
}
}
# in an OO module
sub print_stats {
$_[0]->{fh}->stats();
}
# lastly, co-workers are often confussed by :
use strict;
I am sure there are others, but these are ones i have had in the past few weeks.
$ perl -e 'do() || ! do() ;'
Undefined subroutine &main::try
