Title: Fixed MSVC 9.0 warning C4913

MSVC emitted the warning
```
user defined binary operator ',' exists but no overload could convert all operands, default built-in binary operator ',' used
```
for the `operator[]`. The fix splits the `BOOST_ASSERT_MSG` usage and the element access to two statements.
