Comment (by mjklaim@…):

 As you will see in the example attached (tests uses Google Test) the call
 to find allow different types of keys than the underlying value type, as
 expressed in the "unique_key_values" test.

 Unfortunately I had to write a custom "find" function in the
 AnyValueSet::SetOf class, so that the key is used to compare directly with
 the value, both types being preserved.

 Fortunately, flat_set being basically a vector, it's not really a problem
 on performance to write the search this way.

 Anyway, I wanted to give my use case. The find function could be
 simplified by just providing the key to flat_set instead of having to do
 the search manually.
