So maybe something more like this:

class X

   def initialize
     @foo = 0
   end
   def ready?
    @foo += 1
    @foo = 50
   end

end

def _when(condition, &block)
   until condition.ready?
     sleep 0.1
   end
   block.call
end

x = X.new

_when(x) { puts "It's Ready!" }

#=> It's Ready!

	when is already a keyword so you will have to come up with a better  
name but this kind of does what you want.
