Here's a strange concept that I don't really know how to implement, but
I suspect can be implemented via descriptors or metaclasses somehow:
I want a class that, when instantiated, only defines certain methods if
a global indicates it is okay to have those methods. So I want something
like:
global allow
allow = ["foo","bar"]
class A:
def foo():
...
def bar():
...
def baz():
...
any instance of A will only have a.foo() and a.bar() but no a.baz()
because it wasn't in the allow list.
I hope that makes sense.
Don't ask why I would need such a strange animal, I just do. I'm just
not sure how to approach it.
Should class A have some special metaclass that prevents those methods
from existing? Should I override __new__ or something? Should those
methods be wrapped with special property subclasses that prevent access
if they're not in the list? What's a low-overhead approach that will
work simply?
Thanks in advance,
-David
