Description Vlad Levenfeld 2014-05-02 21:01:42 UTC 
this test passes:
  uint x = 0;
  (x += 1) %= 2;
  assert (x == 1);
  ubyte y = 0;
  (y += 1) %= 2;
  assert (y == 0);
  // though I expected y == 1
  y += 1;
  y %= 2;
  assert (y == 1);
  // this is correct

using dmd from debian package dmd-bin v2.065.0-0

This is working since 2.067.1 according to run.dlang.io

void main()
{
  uint x = 0;
  (x += 1) %= 2;
  assert (x == 1);
  ubyte y = 0;
  (y += 1) %= 2;
  assert (y == 1);
  y += 1;
  y %= 2;
  assert (y == 0);
}
