that'dnot correctly work for subsequent uses of the statement if the variable differs - don't think we'd have replacing

If we were going to fix this, then it would probably be because of the
issue around it working inconsistently when the variable differs over
multiple calls. That's something that we've heard about at least once
before. I'm not excited about fixing the ambiguity issue.

I don't know.
