This code fails the assertion:
import std.algorithm;
import std.stdio;
void main()
{
string[] x = ["_10", "_20", "_100"];
assert(isSorted!"a.length < b.length ? true : a < b"(x));
}
However, it _is_ sorted according to the predicate, so the assertion should
pass.
I ran into this because sort throws an AssertError sorting ["_100", "_10",
"_20"] using that predicate, claiming that the sorting failed, when it actually
succeeded. So, not only is this messing up isSorted, but it messes up sort in
non-release mode.
