I feel strange when I see these are not equivalent:

  def foo1 &block
    block.call &bar
  end

  def foo2
    Proc.new.call &bar
  end

  def foo3 &block
    yield &bar
  end

The middle one may be a weird idiom that should be phased out, but I
really think that calling a block captured into a variable should be
equivalent to using yield.

If foo1 and foo3 are not equivalent, then we have an inconsistency.
