Hi,

I've written a small wrapper for std::map::find() (and map-like
containers/ranges) that returns a pointer to the value if found (or
NULL if not found).

See https://svn.boost.org/trac/boost/ticket/5227

The advantage is that you don't need the container type name (for
::reference), you can initialize the pointer inside an if condition,
you don't have to compare against ::end() and you don't have to use
->second.
For containers of pointers to objects, the wrapper could do an
additional dereference.

Do you think this would be useful for inclusion in Boost?

Greetings,

Olaf
