The reference to self is bound to the methods by the way you look them up.

If the list is static, there is no need to calculate it more than once, 
at class-definition time.  I might do this like so:

class CustomMethod:
...
     all_methods = [method1, method2, method3]
     def apply_all(self):
         for m in self.all_methods:
             m(self)

Class code has access to the results of previous class code.
