define method hook

[Ben Burkert]

Is there a way to intercept method defines, so that i can setup a
callback whenever a new method is defined for a class? I'm looking
for something that works with the def keyword, and doesn't require
any extensions.

Yep. Module#method_added
If you do this:

class Example
def self.method_added(meth)
p meth
end
end

After that, this code:
class Example;def foo(baz);5;end;end

..will print out: :foo

class Module
def method_added(method_name)
p [caller[0], self, method_name]
end
end

class Foo
def bar
end
end
