Comment (by Agustín K-ballo Bergé <kaballo86@…>):

 We have discussed this on IRC with alfC, and come to the conclusion that
 the underlying issue is that `result_of::invoke` is not SFINAE-friendly
 (as defined by C++11). The proper fix for this issue is then to make it
 SFINAE-friendly for all C++ versions.

 Additionally, there are two `invoke` definitions: one for `Sequence&` and
 another one for `Sequence const&`. This is redundant at best, and should
 be simplified.
