[code-quality] assigning node type with function annotations?

[Jarrad Hope]

Ahh thank-you so much!

I ended up with this so I can define list, seq, dict, etc

def argument_annotation_inference(node, context=None):
        _type = next(node._annotype.infer())
        klass = vars(builtins)[_type.name]
        return iter([CONST_CLS[klass](klass())])
