Just out of curiosity, what's a "naive type vector"?
A type vector you might implement after thinking about it for 5 minutes.
Sorry, I mistakingly read it as a "NATIVE type vector" :)
You mean iterators? What makes you think their presence is going to cause compilation to slow down?
Well, iterators are separate templates, and require to be instantiated...
Only if used. The template does need to be parsed, but that's not a big hit. mpl::at<some_mpl_vector, N>::type doesn't use iterators.
Also if you dereference them through meta-function, like mpl::dereference<Iter>::type, that's one more instantiation.
Of course, but only if you use iterators.
Of course, if used. What I meant is that if you want to get all elements of an mpl::vector<> it _might_ be faster to get them by index rather then through iterators... Regards, Arkadiy
