[Python-bugs-list] [Bug #117241] class.method(*([self]+args)) gave me a 'unbound method must be called with class instance 1st argument" error message.

Bug #117241, was updated on 2000-Oct-18 15:28
Here is a current snapshot of the bug.

Project: Python
Category: Parser/Compiler
Status: Open
Resolution: None
Bug Group: None
Priority: 7
Summary: class.method(*([self]+args)) gave me a 'unbound method must be called with class instance 1st argument" error message.

Details: I have some 1.5 code like this:

apply(BaseMsgTemplate.__call__,[self]+args)

This works great and does what I want, calls the base class call method
with the current instance as self.  I thought I'd convert it to the
new calling syntax:

BaseMsgTemplate.__call__(*([self]+args))

But this gave me the error message:

'unbound method must be called with class instance 1st argument'

I *think* the * argument method is supposed to be functionally
equivalent to apply, so I think this is a bug.

Comment:
Definitely a bug! A simpler example would be Base.__init__(*(self, arg)).
