I have to say, I agree, this would be a REALLY nice
feature for the language to have. Hmm... I'm not sure
I'm quite up to channeling Guido, but I hear this vague
ectoplasmic echo saying:
      "so... show me the patch!"
Not that (optional) lazy evaluation wouldn't be nice at
times, but it's rather difficult without impacting
performance of the entire language.
