If you are willing to delegate the actual work to the metaclass call:
def register(f):
f.registered = True
return f
def registered(name, bases, namespace):
namespace["my_cool_functions"] = [
n for n, v in namespace.items()
if getattr(v, "registered", False)
]
return type(name, bases, namespace)
class MyClass(metaclass=registered) :
@register
def foo(self):
pass
@register
def bar(self):
pass
def other(self):
pass
print(MyClass.my_cool_functions)
