Varying return types has always caused problem for me down the road. Best thing to do might be to always return ref regardless of the number of parameters you receive.

I think a hashref here is a better return value than an array ref. Perl already has hashes built in. If you return an array ref, you are forcing the user of your API to re-implement associative arrays.
