Subject: [ruby-core:41787] Breaking while loading

Hi!

Here���s a problem that I���m not surprised hasn���t come up before.
Breaking an iteration from inside a load raises LocalJumpError.

Is this a bug?

If not, how do I work around it?

b.rb:
$block.call 1
$block.call 2
$block.call 3

class A
  include Enumerable

  def each(&block)
    $block = block
    load 'b.rb', true
    self
  end
end

p A.new.take_while{ |i| i < 3 }

% ruby -v
