In hindsight my post should have read more like:

- No compiler would treat the condition as an error. A warning, Yes. But not an error.

- There are plenty of DB tools (IBExpert for one) which perform their own "syntax checking" and report warnings (though I would need to test if IBE reports a warning for this case).

- AFAIK, the FB engine only reports errors. So, a new set of functions/methods would need to be developed to report and handle warnings.
