in reply to Hash references moving between modules
Turns out this was a trick question--the thing that I thought was a hashref really was. It was the next line with the grep that was failing. That regex should have been /^gene/ instead. As a result, the @keys array was empty, making it look later on like I didn't having anything in the hash.
D'oh!
Thanks anyway,
