One of the only languages that compiles to a high level language such as C, Vala has interested me for quite a bit. I've been wanting to start a small project with it, but I've been wondering how I would distribute it.
The fact is, that it compiles to C code (C99 I suppose).
From a Vala developer in irc, #vala on irc.gnome.org:
18:57 < flo> It is of course possible to distribute the C code as
well. The compiler itself is shiped with vala and C code. We
actually access C-libraries over an abstract interface with all
advantages and disadvantages of the libraries we are using,
including platform dependencies.
