[New-bugs-announce] [issue27157] Unhelpful error message when one calls a subclass of type

[ppperry]

New submission from ppperry:

>>>class x(type):pass
>>> x(x)
Traceback (most recent call last):
  File "<pyshell#335>", line 1, in <module>
    x(x)
TypeError: type() takes 1 or 3 arguments

I am giving it one argument, and yet it's complaining that `type` expects one or three arguments. How unhelpful.
