some time ago I wrote a class called numbered_set. It was like a set (i.e
efficiently checked for duplicates) but had additional integer index, so
that all elements could be obtained by the index in constant time.
Will it be possible to mimic this functionality using your library? I've
quickly browsed the docs and did not find if it's possible.
One more small comment. The 'tagged indices' might not be the right
solution: they mean that I need to introduce more-or-less global type
'name' just because I want to store employee in an indexed_set. Is it
workable to use 'member' function to specify index. E.g. instead of
typedef employee_set::index_type<name>::type employee_set_by_name;
member<employee, std::string, &employee::name> >::type
I also think that
member<employee, std::string, &employee::name>
is too verbose, though I'm not all all sure it can be made shorter.
And the final note: what if employee::name is a method, not member variable?
This does not seem to be supported. It it by design, technical problems or
lack of time?
