Why can the procedure 'regexp' be called with an already compiled <re>

Convenience, I'd say.  That way you can create modules which have an
interface that accepts either SREs or regexp objects (like irregex does),
having it automatically compile SREs.

I propose dropping the requirement that 'regexp' can be called with an already compiled <re>. It provides no additional functionality and it makes the specification of 'regexp' less clear.
