[Vala] Immutable variables

[pancake <pancake youterm com>]

Is there a way to define them? I need it to solve some warnings for  
the vapis describing some C functions accepting const char* as argument.

As I see in the compiler source is that it is not supported. Only for  
struct or class definitions with [Immutable].

Are there plans to support it for variables?if it is just to handle  
function signatures correctly..

The problem is not only the warnings. Because I'm using libvala to get  
C signature info from vapi files. And not having a way to describe  
this is problematic.
