Re: [Boost-users] Can't call boost::fusion::invoke with >= 7 args

Thanks!

If I may make a couple of suggestions:

1. Add a comment in invoke.hpp line 102 that if you get the error I just 
saw, that's what you need to do.
2. Add a similar comment to the documentation for boost::fusion::invoke

These are the first places I looked. I thought the problem was in my own 
code at first, so spent a lot of time before I was able to write a 
sensible list post. :)
