Subject: Object#undef_method ???

Folks,

You can remove a method from a class or module using Module#remove_method
and Module#undef_method.  What if the method you are trying to get rid of
is a _singleton_ method?

For instance,

  module X
    def X.foo() 4 end
  end

  X.foo           # -> 4

  # Some code goes here.

  X.foo           # -> NameError: undefined method `foo' for X:module [1]

Please write the code in the placeholder.

[1] Or 'NoMethodError'; I can't tell which is which.

A related question.  I want to remove a method and redefine it.  Why not
just overwrite it?  Because that raises a warning.  I don't want to run
the code without warnings, and I don't want to have to fiddle with the
warning level at runtime.  Any comments appreciated.

Cheers,
Gavin
