This will only get attributes defined in SomeObject.__class__ - not the
one defined in the parent classes. Nor methods dynamically bound to a
specific instance.

You *still* don't need eval here.
target = <module or any other objet here>
for funcname in funclist:
func = getattr(target, funcname, None)
if callable(func):
func(*args, **kwargs)
I've almost never had a real use case for eval (or exec) in 7 years.
