           Summary: CTFE: foreach(Tuple) won't compile if Tuple contains
                    string

Oddly, it compiles if you commment out the ; -- the foreach has to be
non-empty. Behaviour is quite odd; if there are several items in the tuple, it
will work if you don't use the whole tuple; eg Types[0..$-1] and Types[1..$]
will work. So it sounds like some kind of memory corruption/unterminated string
or similar.

Possibly the root cause of some of the bugs in issue 1298.

bug.d(9): Error: cannot evaluate foo() at compile time

int foo(Types...)() {
    foreach(T; Types) {
        ;   // will compile if you remove this line
    }
    return 0;
}

const int q = foo!("")();
