i'm not convinced in_out is the way to go, but using
pointers is very far from conveying the same information:

pointers can be 0, while references and in_outs can't,
and the reason behind using a pointer is often exactly
this (an "optional" parameter)

pointers can point to arrays, while references and in_outs
can't, and imho this is the most frequent reason behind using
a pointer

pointers can point to const data, while in_outs can't, and
that would be the reason behind using in_outs...
