That wouldn't be enough because proto::matches "knows" about
proto::switch_. It would be easy enough to extend proto::switch_ to take
an optional mpl metafunction that accepts and expression and returns a
type to dispatch on. It would default to proto::tag_of<mpl::_>. Or for
the sake of consistency with the rest of proto, it should probably be a
transform, in which case it would default to proto::tag_of<proto::_>().
OK
Could you open a feature request?
Well, we wanted to know the correct road, i have someone to do it, so
let's say we'll provide you with a patch request instead ;)
Even better. :-)
Here is a first try:
https://github.com/MetaScale/nt2/blob/30251fccec639a3823179fc04100fb3fba0688b2/modules/sdk/include/nt2/sdk/dsl/select.hpp
Not sure it is perfect but it works eemingly :)
