Say I 'd to get src_val from the find function, what should I do?
You need to either define operator==(const _myval&, const string&) that
would compare the struct's src_val field to a given string, or else
write a comparison predicate doing the same and use find_if.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
