Thanks! That function seems to do exactly what I need. However,
is it expected to work using boost::tuples? (I tried using
fusion::vectors and it works perfectly.)

The issue I'm running into is that remove() returns a filter_view,
which, I'm guessing, is convertible to a fusion::vector but not to
a boost::tuple. Is there any way to make that latter conversion work?

I've already included:

#include <boost/fusion/include/remove.hpp>
#include <boost/fusion/adapted/boost_tuple.hpp>

But it looks like boost::tuple isn't being adapted fully.

Thanks again.
