This is simply to rescue me when I have not had enough coffee or can't see the woods for the trees. I recently spent wading through some code for a few hours and lo and behold: I had used a single "=" instead of a "==" (as in if (x ==testvar)). As you might guess I *have* been down this road before ... yes, I do know better and with all of the attendant variable re-assignment fun of this mistake.
A button or special highlighting to check code for inappropriate (likely) use of the equality operator(s) would be handy.
It's would be one of those little nice-to-have's ... in 4.0 or whenever ...
