No, what I heard is that, since in *most* cases the string quotes are not needed, people are surprised and annoyed when they encounter cases where they are needed.
Well, I had assumed quotes would be used in all cases for consistency.
That does seem like a reasonable solution. Redundant, ugly, and annoying, but safe and consistent. Sort of like using type constraints in the first place. :D

Nope. "--" sometimes means "ignore the rest of the line, including the ")". At the moment, I can't remember where I've seen this outside of SQL, but I can guarantee that if I read it late enough at night, the *best* case would be that I notice the ambiguity, guess correctly and am only annoyed. -jJ
