The isinstance condition, added in #7108, was never true - each BuiltinFilter run of this test uses a BuiltinFilter class, not an instance. So this corrects it.

Can we make this a function instead?

If there's a reason to prefer functions, then maybe they should all be changed.
I'd suggest a common function for all three, except that this uses a float and those other two use double.

Functions are generally safer than macros, which need extra care around parentheses and don't get extra checking. But if this is a copy/paste of existing ones then we should be fine.
