I do not propose to change the current behavior. I propose to add new
named constructors. In most cases default constructors can be used, but
in cases when we use type check or different tricks to limit the type of
the argument, we could use named constructors.

Current named constructors:

* dict.fromkeys()
* int.from_bytes()
* float.fromhex()
* bytes.fromhex()
* bytearray.fromhex()
