I don't think it makes semantic sense for exists to be applied to functions. Exists applies to aggregates (hashes originally, later extended to arrays, where the semantics are slightly more dubious).

What's the matter with defined &foo?

Exists can't be applied to simple vars since there isn't sufficient state stored to be able to distingish between 'always been undef' and 'had a value, now undef'.
