I think you need TypeInfo.getHash.

   https://dlang.org/phobos/object.html#.TypeInfo.getHash

import std.conv;

auto myHashOf(T)(auto ref T value) {
     return typeid(T).getHash(&value);
}

void main() {
     auto x = 1;
     auto s = "1";
     assert(myHashOf(x.to!string) == myHashOf(x.to!string));
     assert(myHashOf(s) == myHashOf(s));
     assert(myHashOf(s) == myHashOf(x.to!string));
}
