= force_bind

Adds UnboundMethod#force_bind to bind an unbound method to class (or any object of any type).

It basically bypasses the argument type checking that #bind has.

== Requirements

* Ruby 1.9.1 or greater (does not work in Ruby 1.8.x)

== Example

Bind an instance method to its class (making it act like a class method):

  class Foo

    def bar

      puts "I'm inside #{self}"

    end

  end

  

  Foo.new.bar

  #=> "I'm inside #"

  

  meth = Foo.instance_method(:bar).force_bind(Foo)

  meth.call

  #=> "I'm inside Foo"

    

You can also use this to rebind the instance method of any object to any

other object:

  class A

    def foo; self end

  end

  

  class B; end

  

  meth = A.instance_method(:foo).force_bind(B.new)

  meth.call

  #=> #
