Sounds like next_method in generic functions, which is an area of
generic functions we haven't touched upon (but which seem important). I
think in RuleDispatch it goes like:
@foo.when(...)
def incremented_foo(next_method, arg1, arg2):
return next_method(arg1, arg2) + 1
By using a first argument named "next_method" you tell the generic
function machinery to pass in this special object, which acts like the
original generic function ("foo" in this case) but ignores the current
method.
I assume there won't be very positive reaction here to behavior based on
an argument name. But ignoring that aspect, it's a somewhat important
feature of typical generic function implementations, and very similar to
super.
