This seems very wrong to me. Calling through a method object should 
behave the same for super as calling directly or calling through an alias:


class Foo
   def a; puts 'Foo a'; end
   def b; puts 'Foo b'; end
end

class Bar < Foo
   def a; puts 'Bar a'; super; end
   alias b a
end

Bar.new.a # => "Bar a\nFoo a"
Bar.new.b # => "Bar a\nFoo a"
Bar.new.method(:b).call # => "Bar a\nFoo b"


It seems incorrect for method objects to change the behavior of super. 
If I super in 'a', I want super's 'a' to be called, without exception.

Can someone confirm this is a bug? In JRuby we always super up the 
same-named chain, so this represents an incompatibility.
