The problem is not really what enhancement to do. But what limit
do we fix to ourselves (ie, what is a bug and what is not).

There are possibilities to do more, but compatibility require
that we put the line somewhere.

The current line seems to be to do VRP on expression and compile
time know values. Is that right ?
