I'm very interested in fusion and have been experimenting with it.
There is one thing that is currently confusing me. (OK more than one thing). The documentation a typical function at .../fusion/sequence/concepts/associative_sequence.html shows valid expression
has_key<K>(s)
returning type
result_of::has_key<S, K>::type
which is OK by me. But why doesn't fusion use:
#include <boost/result_of.hpp> then use boost::result_of<has_key<K>(S)>::type
which would seem to me to reduce the size of fusion (and the docs) by around 50%. What am I missing here?
That boost::result_of does not work with plain old free functions.
