Re: New warning from compiler about loop variables

[brian <brian@xxxxxxxxxxxxxxxx>]

The issue is if you declare a var and use it for something . And then by accident use and declare the same one in a loop. There was no error or warning you are left debugging ....
Guilty as myself of that. Every other language would make that an error.
