Test file.

The attached code implements the int() operator as well as
operator[](std::string).

The following snippet:
Test a;
a["hello"];

compiles on gcc, using the operator[] overload.
On clang, it complains of an ambiguous call. It seems that if there is an
operator[] available, then clang should choose that option rather than thinking
it is an index into a string.
