Ahh, looks like it is leaking PowExp::toElem - didn't notice this as I have it
implemented in GDC.

Best thing to immediately do is implement the missing methods as stubs (I was
intending to move onto backend support and add constant folding/ctfe support
for ^^ operations. :)

Can you see if you can break things in any way after this commit?

 Can you see if you can break things in any way after this commit?

Now this code doesn't crash DMD:

void main() {
    auto _ = [1][] ^^ 2;
}


But this code doesn't work yet:

import std.math;
void main() {
    int[5] a, b;
    b[] = a[] ^^ 2;
}


It gives:

...\dmd2\src\phobos\std\math.d(58): Error: module math is in file
'core\stdc\math.d' which cannot be read

Sorry, my Phobos was badly set. Things work now.
