Just remember not to confuse Data::Dumper->Dump, and dump.

I misremembered how to use Data::Dumper once, and wrote something like:

use Data::Dumper;

my $a;

# build up complex thingy in $a

# dump it out to try to debug what's wrong with it
print dump($a);

Took me quite a while to realize that Data::Dumper wasn't what was core dumping my program, the dump built-in was... :)
