rebound

By default, instances of UnboundMethod can only be bound to objects that
are a kind_of? the method’s original class. Pretty lame.

rebound allows unbound methods (instances of UnboundMethod class) to be
bound to objects of any class. It uses the alias_method_chain pattern to
accomplish this, meaning you also get a bind_without_indifference method
that retains the original behavior.

USAGE

class Guy
  def greet
    puts "Hello!"
  end
end

class Girl
  # No #greet method here
end

girl = Girl.new

m = Guy.instance_method(:greet)

m.bind(girl)

girl.greet # => Hello!

TODO:

  • Could probably use some more specs, since I’m pretty sure I didn’t think
    of everything.

REQUIREMENTS:

  • ParseTree
  • Ruby2Ruby

Credit

I’m just standing on Ryan Davis’ shoulders with
this project. He did all the hard work. I just did something cool with it.
(Which isn’t to say that what he did wasn’t cool, since what he did is way
cooler than what you see here.)

Also, Magnus Holm contributed a patch that made things
cleaner behind the scenes.
