This behaviour seems to imply a rather fundamental change to the way that 
Python handles bound methods. At present every time you access foo.bar you 
get a new object created, but I think from your description that you want 
to be able to associate a ccl with all the foo.bar objects.

Or to put it another way:

fn1 = foo3.bar
fn1() // executed okay
fn2 = foo3.bar

 *** EXCEPTION: execute capability barred to "all functions".
 *** ??? What should this do.

If I set a ccl on fn2, should it also affect access to fn1? They are 
separate objects, so shouldn't they have separate ccls? If they share a 
common ccl, then how is it going to be stored without impacting heavily on 
every method call?
