In my code if I add an
x = 1

I get a warning #8, but I want the compiler to give me an error, and not let me make a mistake in a variable definition.
After so many years, I don't know how I didn't realize this functionality before or when it changed.
How do I force all variables to be declared and not get a warning, but an error?

thinking about how it happened to me, it was due to a search and replace in the entire project, I made a mistake in one letter, and that's where the error came from. I will have to review all the notices of my project or see how I locate the notices of only that type to correct them.

idea: view/localize warning by type.
Thanks, erel, one more time!!!
