Bug with std.string.indexOf and case sensivity

Nevermind that.
For some reasons, the bug was happening when my main.d file 
looked like this:

import std.stdio;
//import std.string; // will work when imported

int main()
{
  string str = "Les chemises";
  // doesnt work
  write(std.string.indexOf(str, "Les", CaseSensivity.yes));
  return 0;
}

---
While it works when importing std.string. Note that I was using 
exactly the same enum (at least, I thought ?) than std.string

enum CaseSensivity { no, yes }

Whatever, it works now. I just need to don't forget to import 
std.string.
