Any reason why you type all of
require Data::Dumper;
print Data::Dumper::Dumper(...);
rather than
use Data::Dumper;
print Dumper(...);
?
Also, in your particular example, I always prefer the output of Dumper(\%hash) to that of Dumper(%hash).
Recently, I've been sometimes using the even-less-typing-required use YAML; print Dump(...), but that requires actually installing YAML first. And I'm still not nearly as used to the YAML format as I am to Data::Dumper format.
