void doExclude(string exclude) { string[string] aa; int[] keep; foreach(int i, h; ["a", "b"]) { auto ptr = h in aa; pragma(msg, typeof(ptr)); // string* pragma(msg, typeof(*ptr)); // string if(*h != exclude) keep ~= i; } } test.d(9): Error: incompatible types for ((*cast(immutable(char)*)h) != (exclude)): 'immutable(char)' and 'string'

(Slaps self in forehead.) Never mind, I see what I did now. I used *h where I meant *ptr and forgot that strings implicitly convert to char*.
