Hi,
I'm using fusion::result_of::as_vector<some_mpl_transform_view>::type
quite frequently, but having troubles with extremely long type names (our vc8.pdb are close to 0.5 Gb).
Is there any way in fusion like in mpl, where one can do mpl::vector<a, b, c>::type ^^ which gives the shorter name mpl::vector3<a, b, c> instead of mpl::vector<a, b, c, na, na, na, ...>
In essence, can I have fusion::vector2<int, float> from the following:
fusion::result_of::as_vector<mpl::vector<int, float>::type >::type
There's actually a typedef vector_n that gives the type of the numbered vector contained. Alas, it's private. I'm not sure if I want to make it public. I can provide an easy solution for you: template < BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT( FUSION_MAX_VECTOR_SIZE, typename T, void_) > struct make_vector_n { typedef typename detail::vector_n_chooser< BOOST_PP_ENUM_PARAMS(FUSION_MAX_VECTOR_SIZE, T)>::type type; }; If that works for you, would you provide simple docs for it I can add in the reference?
Thanks for a great lib!
