[svn r137] Many fixes towards tango.io.Console working, but not quite there yet... In particular, assertions has been fixed to include file/line info, and much more!

module bug80;

void main()
{
    byte b = 10;
    int i = b += 2;
    printf("byte=%d int=%d\n", b, i);
    assert(b == 12);
    assert(i == 12);
}
