Don't know whether it counts as "obvious", but I
think there is a way (short of using exec):

   import new
   g = new.function(f.func_code, B.__dict__)

This creates a new function g which has the
same code as f but a different global namespace.

(You can't just change f.func_globals directly
because it's a read-only attribute, unfortunately.)
