I understand the concept of some_instance.send but I'm trying to figure out why you can call this both ways? The Ruby Koans imply that there is some reason beyond providing lots of different ways to do the same thing and I'm wrestling with figuring this out. Here are the two examples of usage more concretely

class Foo def bar? true end end

foo = Foo.new foo.send(:bar?) foo.send(:bar?)

Anyone have any idea about this?

thanks in advance!
