-/**
- * LLTypeInfoLookup is specifically designed for use cases for which you might
- * consider std::map<std::type_info*, VALUE>. We have several such data
- * structures in the viewer. The trouble with them is that at least on Linux,
- * you can't rely on always getting the same std::type_info* for a given type:
- * different load modules will produce different std::type_info*.
- * LLTypeInfoLookup contains a workaround to address this issue.
- *
- * The API deliberately diverges from std::map in several respects:
- * * It avoids iterators, not only begin()/end() but also as return values
- *   from insert() and find(). This bypasses transform_iterator overhead.
- * * Since we literally use compile-time types as keys, the essential insert()
- *   and find() methods accept the key type as a @em template parameter,
- *   accepting and returning value_type as a normal runtime value. This is to
- *   permit future optimization (e.g. compile-time type hashing) without
- *   changing the API.
