I would agree with you completely if the question had been "Why
does this code generate a Constraint_Error?" But it wasn't, so
I pointed out an unrelated minor typo in passing. Maybe he hit
the key next to the 4 by mistake. Maybe it was a deliberate error
to generate Constraint_Error for testing purposes.

I know you don't like people giving direct answers to questions,
but I hadn't realised this also extended to questions that haven't
even been asked...
