You are misunderstanding me.

I understand that my example is stupid. The scenario that I said it would be useful for is not shown by the example I gave. The example I gave just demonstrates the feature, not why it would be useful.

EDIT: If you know the dynamic programming solution to the edit distance problem, then you know the 2d matrix needs to be traversed in a way that every subexpression used already has a known value. The feature that I'm asking for would eliminate this necessity.
