digitalmars.D.bugs - [Issue 12782] New: Wrong foreach mutable index implicit conversion


          Issue ID: 12782
           Summary: Wrong foreach mutable index implicit conversion error
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: rejects-valid
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: bearophile_hugs eml.cc

Apparently the bug fix of Issue 9570 is not able to handle this case, so this
is a new enhancement request. I think this code should be accepted:

void main() {
    ubyte[256] data;
    foreach (ubyte i, ref x; data) {
        i += 200;
        i = 200;
        x = i;

With dmd 2.066alpha it gives:

temp.d(3,5): Error: index type 'ubyte' cannot cover index range 0..256
