It is a huge undertaking to make a new mapping, but if there is enough
interest we do see some options to start the work. It needs funding by
some users but more importantly we need good ideas and feedback from the
C++ community, let us not get another bad mapping

Please share ideas of how things could look like, for example, what do
we do for the _var/_ptr/_narrow, how would this look like with a new
mapping. We can easily use std::string, std::vector, but especially
_var/_ptr replacement is very important.
