- The functor can be passed by reference with <tt>boost:ref</tt>
If the item with key equal to \p key is not found the function return \p false.
\endcode
where \p item is the item found, \p key is the <tt>find</tt> function argument.
- You can pass \p f argument by value or by reference using \p std::ref.

The functor can change non-key fields of \p item. Note that the functor is only guarantee
that \p item cannot be disposed during functor is executing.
The functor does not serialize simultaneous access to the set \p item. If such access is
