[Vala] bindings from vapi

[pancake <pancake youterm com>]

I am planning to write a tool to generate bindings for Python/.NET/Perl/...

My idea is to parse the vapi files and based on the signatures of the 
functions
create the necesary stub to have the bindings for other languages. GIR 
and related
are designed for GObject bindings.

What I'm thinking is to do the same for non-gobject bindings. This is 
because
Vala (in vapi files) allows to describe in a much better way the 
function signatures
(like direction of refs, and out parameters) which C doesn't.

I wrote some manual proof of concepts and I think that .net, python and 
lua bindings
will be an easy task.

I had not written anything yet, but I'm really interested on this for 
many reasons,
(some projects of mine) and I would like to know your opinion and tips 
about how to
face this.

Should I use libvala? like valadoc does? Is there any example code 
iterating over
methods, namespaces, arguments of signatures, etc..?

Thanks!
