Subject: Re: convert yield to proc

My bad.

Looked at the original post, and here's the problem:

class Bar
  def foo
    #stuff
  end
end

def baz1(&blk)
  Bar.new.instance_eval &blk
end

def baz2
  baz1 &lambda { yield }
end

baz2 { foo }

When you yield to the block for baz2, it tries to call the method foo of a
Bar object, but it's not actually being instance_evaled, only the { yield }
block is being instance evaled, so you get an undefined method error.

Thanks for correcting me.
