For these special cases, there exists no optional argument type. Since a endless method is started with
=, there was ambiguity here. We have to simply reject these in all cases.This adds a new error for the following reason:
def foo arg = nilis interpreted as a normal method call with optionalargwithout matchingenddef foo *arg = nil; endis interpreted as a endless method call that has bodynilwith extraneousenddef foo *arg = nilis somewhere inbetween and I don't know how to otherwise indicate the error.Now the second case above also shows the newly added error message.
