Removing methods from an inherited class

[Iñaki Baz Castillo]

Hi, if class A contains method "hello" and class B inherits from A, is
it possible to remove method "hello" in the definition of class B?
Maybe a workaround could be making "hello" method private in class B.

NOTE: I do know that I can override "hello" method (something as "def
hello; nil; end") but I don't want it.

Thanks for any suggestion.

Are you looking to do this to make it use A#hello instead of B#hello ? If
so, you might consider using `super`. That aside, you can look at
Kernel#undef_method and Kernel#remove_method (the two have different
semantics).

Kernel#undef_method is exactly what I was looking for

Thanks a lot.
