PJE seems to have borrowed the time machine :-). Based on the code the
register function is already a decorator:
def register(typ, func=None):
if func is None:
return lambda f: register(typ, f)
registry[typ] = func
return func
The returned lambda is a one argument decorator. so your syntax:
@generic_fn.register(XXX)
def xxx_impl(xxx):
pass
Already works. A test to validate this behavior should probably be added.
I don't mean to bikeshed, but could we call this function
functools.generic instead of functools.simplegeneric? The only reason I
can think of for keeping it simplegeneric would be to avoid a future
name clash with the Generic Function PEP and if/when that PEP get's
implemented, I would think that the functionality would live in
builtins, not functools.
