[Python-ideas] make __closure__ writable

[Mark Shannon]

Whoops, cut and paste error.

The code should have read:
> 
> def f_with_new_closure(f, closure):
>     return types.FunctionType(f.__code__,
>                               f.__globals__,
>                               f.__name__,
>                               f.__defaults__,
>                               closure)
> 
> def modifier(func, closure):
>     if func.__wrapped__:
>         while func.__wrapped__.__wrapped__:
>             func = func.__wrapped__
>         func.__wrapped__ = f_with_new_closure(func.__wrapped__,
>                                               closure)
 >         return func
>     else:
>         return f_with_new_closure(func, closure)

Cheers,
Mark.
