RCR: def method...end return a method object

ruby-talk
1

Currently if I want to "do something" to a method after it's defined, I
basically have to do

def method
# stuff
end
do_something_to_method :method

(or hook onto method_added).

This is surprising since typically with ruby constructs you can use them
as blocks, like

a.compact{}.uniq.whatever

Proposal:
Change def to return a Method instance [1]

which would allow construct like
def method

end.do_something_to_it

Feedbacks?
-r

#method always returns a copy of a method, not the original. Presumably def would have to do the same thing, rendering it a lot less useful. I'd rather it return the name defined as a symbol, but honestly I think that constructs like your example:

def method

end.do_something_to_it

are unclear. Constructs should generally do one thing only. In this case, define a method.

in addition to #15 @ http://rcrchive.net/ (except that it doesn't seem
to be working right now).
