--- Comment #5 from dlang at croco-puzzle.com ---
In my oppinion aa[0]++ should behave exactly the same as aa[0] = aa[0]+1.
Therefore in my oppinion a correct unittest would be:

unittest 
{
    import std.exception: assertThrown;
    import core.exception: RangeError;

    double[int] aa;
    assertThrown!RangeError(aa[0]++);
}

(At the moment with dmd v2.082.0 this leads to a segmentation fault, while
with ldc2 1.12.0 and gdc 8.3.0 I get the expected "assertThrown failed".)
