TableGen is far more declarative that procedural. Even something simple like using a "for each" type syntax and refering to the construct as a "for each definition" would go a long way. What I want to avoid is any implication that there's a guarantee for order of evaluation.

Another thing that needs clarification is the multiple variable syntax:

  for x = [1, 2, 3], y = [4, 5, 6] in { … }

It is not clear if you get a cross product or a 'zip'.
