"Implicitly converted" meaning it exists as something else and 
can be converted to it. If you don't want the GC then don't use a 
string.

      @nogc:

      int stuff = 4;
      auto t = i"my interpolated %stuff string";
      string s = mallocString(t); // no different than having to 
call malloc() + snprintf()
