Make method_missing to lookup in constants too

Description

=begin
First letter of constant is always a capital letter(in Ruby).
if you define method:

def Hi
1
end

You're not able to use it w/o ():
Hi
it looks up for constant and raises error. only:
Hi() or send(:Hi)

None of code style guides teaches to use capital letters in methods' names. It's not convinient and bad practise.
At the same time we use constants(it's modules/classes too) a lot. To access constant we use '(({::}))'

The idea is to change the way how ruby looks up:
(1) if first letter is capital - looking for constant. if not found - moving directly to step 2
(2) looking for local variable and method as we do it now

This change will make syntax much more awesome & sexy:
ActiveSupport::Autoload -> ActiveSupport.Autoload
class Request < Rack::Request -> class Request < Rack.Request

Currently I can give you a hence using this monkey patch:
class Module
alias method_missing const_get
end
module A
module B
class C
end
end
end
#A.B.C instead of A::B::C - awesome?!

For me it is similar to changing hash syntax( => to sym: ''). I know, it is only 1 character less BUT it's 3 visible dots less too :)
Thank you for considering this proposal.
