Can't call __new__ directly to create instances.

[cthulahoops]

This should work, but doesn't:

int.__new__(int, 5)

I think type.__new__ gets called instead of int.__new__, given this:

>>>>> object.__new__(object) 
<class 'type'>

I was pretty sure there was a problem with getattribute, but I've been waiting for a good example to fix.

This works now! I do not know what fixed it, but it works :)

[cthulahoops]

builtins.rs:

    // Special case: __new__ must be looked up on the metaclass, not the meta-metaclass as
    // per vm.call(metaclass, "__new__", ...)
    let new = metaclass.get_attr("__new__").unwrap();
    let wrapped = vm.call_get_descriptor(new, metaclass)?;

Uh... no, I'm wrong. That's only during type creation, not object creation.

The correct implementation of type.__getattribute__ fixes this. (And we don't even need another special case.)

In theory directly calling __new__ in Python should never be done to avoid weird side-effects. The constructor to override is always __init__.

@cthulahoops this issue can now be closed, right?

[cthulahoops]

Yes, I think this is all fixed now.
