The if statement literally causes a 50x slow down of the code.
(LDC debug, dmd debug takes about 1000 times longer)
template AA(string[] S) {
__gshared int[string] AA;
shared static this() {
int[string] d;
foreach (s; S)
d[s] = 0;
AA = d;
};
}

This will have the performance you want if you don't care whether
it works in CTFE.
