Why would you need to overload the [] operator? I have never come across a practical scenario where this was necessary. Can somebody tell me a practical use case for this.

Err..
std::vector<t>,std::basic_string<t>,std::map<k, v>, andstd::deque<t>?I used this for a class representing a registry key, where
operator[]returned an object representing a registry value with the string between []s.See also, the Spirit Parser Framework, which uses [] for semantic actions.
