I am not enthusiastic about this proposal. I have always liked having
the qualifier in the defmethod form explicitly, because it enhances
Requiring the qualifier would satisfy my stated wants, provided that the
qualifier wasn't optional (so there was only one way to write a primary
method) and wasn't re-interned in the keyword package (so we aren't
However, I don't understand why you think the method-combination type of
a generic function needs to be repeated in the defmethod, while the rest
of the contract of the generic function does not need to be repeated.
It seems to me that the command provided by the programming environment
to remind one of the arguments expected, values returned, and documentation
of the generic function can also remind one of the method-combination type.
If you convince me that the method-combination type deserves special
treatment, then I'll change my proposal to make the qualifier mandatory
instead of prohibited.
