--- Comment #3 from markus.enzenber...@gmail.com ---
The danger that I see right now is that someone runs clazy on code they didn't
write, simply follows the warning to replace left(1) by at(0) and thereby
introduces a new, maybe subtle and rarely triggered bug.

The optimal solution would be that clazy recognizes if a check for size 0
already exists in the code.

But as a short-time fix, maybe the warning message could be improved to mention
that left(1) can be replaced by at(0) if the string is not empty?
