If I am trying to make a fusion sequence mpl compatible, do I need to specialize mpl::is_sequence as well?
No. mpl::is_sequence just checks whether mpl::begin returns mpl::void_ (in this case it's not an MPL Sequence).

Thank you for your reply. If I do what you suggest (include intrinsic/mpl), it still doesn't compile. I checked fusion::result_of::begin<myseq>::type was correct but mpl::begin<type>::type is still void_. I'm sure I'm doing something wrong, but I can't figure out what!
I guess you have to make sure that mpl::sequence_tag returns fusion::fusion_sequence_tag. An easy way to do it is to add a 'tag' type member. struct my_seq { typedef fusion::fusion_sequence_tag tag; // ... Regards, Tobias
