 core.exception.AssertError /src/phobos/std/container/array.d(1667): Using out
of bounds indexes on an Array

Should this code[1] really try to access something out of bounds

Also: shouldn't this assertion[2] be perhaps inside 
`version(D_NoBoundsChecks){} else { ... }` block?


Kind regards,
Elias

It's a bug:

     auto s=ar[];
     s.popFront();
     auto s1=s[0..0]; //out of bounds
