digitalmars.D.bugs - [Issue 11841] New: More useful RangeError message


           Summary: More useful RangeError message
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Keywords: diagnostic
          Severity: enhancement
          Priority: P2

Wrong code:

void main() {
    int[10] data;
    int i = 20;
    int j = 30;
    data[i .. j] = 0;

DMD 2.065alpha outputs:

core.exception.RangeError temp(5): Range violation

But I'd like an error message like this:

core.exception.RangeError temp(5): Range violation (20..30 is out of 0..10)

(Optional: if you want in -release -noboundscheck mode the first message
without the bounds is enough, to keep the binary more light.)
