Re: [Boost-users] [fusion][mpl][array] making boost array a conforming mpl sequence (through fusion)

Hi,

I tried to make boost::array a conforming MPL sequence by including:

#include // makes array a conforming fusion sequence #include // makes fusion sequences conforming MPL sequences

but,

typedef boost::array array; assert(boost::mpl::is_sequence<array>::type::value); // fails

Am I misinterpreting the fusion documentation in expecting that this should work? Is there another way of making boost::array an mpl sequence?

I think the basic problem is that is_sequence is not really part of the requirements for an MPL sequence. You don't have to be a conforming MPL sequences. I am not sure how to best approach this. Perhaps the MPL authors have a better idea? Regards, -- Joel de Guzman http://www.boostpro.com http://spirit.sf.net
