           Summary: Associative array with array key often cannot be
                    equated.
           Product: D
           Version: D2
          Platform: Other

Test case 1:
----------------------------------------
void main() {
    int[char[]] a;
    a["h"] = 1;
    assert(a == a.dup); // <-- asserts
}
----------------------------------------

Test case 2:
----------------------------------------
void main() {
    int[immutable(int)[]] a, b;
    a[[1].idup] = 1;
    b[[1].idup] = 1;

}

Hmm, the pull request fixed test case 2, but test case 1 is still failing.

Argh, this is caused by the stupidity of typeid(const(char)[]) using a
different hash function from typeid(char[]) and typeid(immutable(char)[]). Will
submit a pull for this.

Subsidiary fix for issue 6210.

Add builtin typeinfo for const(char)[] so that it will use the same hash
function as char[] and string.
