It looks to me like you are requesting some sort of compile-time
templates, which is certainly not the way vala or C does it. Although I
like the abstract meta-programming features of C++, I think it's way out
of scope to get something like this into vala. As I understand it, vala
is a very thin lean machine between C and C++ targeting Glib and GObject
which allows you to incorporate other libraries (or external exotic
functions) without too much fuss. For compile-time templates or
embedding other languages, you will need a much bigger compiler beastie
to support this properly.
