Overloaded predicates with different arities

[Pieter Van Hertum]

(I couldn't find the issue broes was referering to so i made this new one)

If you have a predicate that is overloaded by 2 predicates with different arities the overloadedtests won't work. Because you find his "parent" by searching in the _name2pred table, which holds the name with arity.
