I recall a discussion about that topic a while ago. I know i felt

Since it actually _is_ a generic from the start, yes, i think it should.
Of course, what i'm really after is a test like 'generic? foo' so that
i can write a macro that does what i think guile should do. Make 'foo'
a generic iff it's not one allready.

Ah, thank's for the clarification.
