Yes, you can use type names.

There is no specific need currently, it just eases writing code
sometimes quite a bit. I wouldn't recommend to always use var as the
readability might suffer but statements like this
        HashMap<string,string> map = new HashMap<string,string> ();
are just nicer to write like that
        var map = new HashMap<string,string> ();

It doesn't make sense, in my opinion, to use it for basic types like
        var b = false;

It's planned to provide API in libvala that will make it easy to write
code completion support.
