Should it be possible to register multiple types for the generic 
function with one register() call, i.e. should:

    @fun.register(int, float)
    def _(arg, verbose=False):
       ...

be allowed as a synonym for

    @fun.register(int)
    @fun.register(float)
    def _(arg, verbose=False):
       ...

Servus,
