AFAIK this cannot be achieved with a metaclass, since the check in `callable` just does a dumb check for `x->ob_type->tp_call`. Seriously, if you know a way to make `x->ob_type->tp_call` run any python code please let me know :-) Thanks, -- Ionel Cristian Mărieș, http://blog.ionelmc.ro

What would be the "right thing"? AFAIK this cannot be achieved with a
metaclass, since the check in `callable` just does a dumb check for
`x->ob_type->tp_call`. Seriously, if you know a way to make
`x->ob_type->tp_call` run any python code please let me know :-)
