Subject: Reflection API -- determining methods' origins

I've been thinking since yesterday about 
#methods and #instance_methods and such.

I don't see any simple way of determining 
whether a method is inherited or mixed in
or whatever. (Singleton methods can be 
detected, I think.)

For example, suppose B inherits from A and
mixes in M.

I could do some array subtraction to take
away the methods from A and M... but that
ignores the possibility that they might be
rewritten in B.

What I'm trying for is a reliably way of
determining the methods that are *defined
in B* (regardless of whether they may be
hiding methods in a parent).

Am I overlooking something here?
