Confused by invalid range error

Explain
1

When I use an invalid range like 2..1 in a for loop, the error I get is something like

src/main.zig:42:11: error: overflow of integer type 'usize' with value '-1'

Why is this the case?

I think it’s a bug, I couldn’t find an existing issue so you should make one, dont forget they moved to codeberg

I wasnt sure if a decreasing range is supported, but it looks like its not.

Either way, I think it’s a bug. The compiler should insert a safety check for the range bounds instead of having an overflow (imo).

Thanks, created one here.
