I ran into a frustrating problem the other day:

$ git add -i
/usr/bin/perl: symbol lookup error: ~/perl5/lib/perl5/x86_64-linux-thread-multi/auto/List/Util/Util.so:
undefined symbol: Perl_xs_apiversion_bootcheck
fatal: 'add--interactive' appears to be a git command, but we were not
able to execute it. Maybe git-add--interactive is broken?

A co-worker came to me today with a curious error message:

use DateTime;
my $date = DateTime->new( year => 2013, month => 4, day => 15 );
$date->set_time_zone("Australia/Sydney");
print $date->today;'

This code gives the error Can't locate object method "_normalize_nanoseconds" via package "2013-04-15T00:00:00" at /usr2/local/perlbrew/perls/perl-5.16.3/lib/site_perl/5.16.3/x86_64-linux-thread-multi/DateTime.pm line 252.

The package "2013-04-15T00:00:00" is the curious part: It looks like a stringified DateTime, but who could possibly be stringifying a DateTime object and then using that as a package name?
