Cool thanks for your input!
I understand that the vala code would be not so readable as to a code
developed by a real developer, but from a maintainability point of view,
what is better? C code or unreadable vala code? :)
Let's see if I have time to investigate your ideas. I would do it as you
suggest, first focus on simple types, and then progress from that.
