Nobody is working on that, as far as I know; it would be nice to get
some examples how to use GTK+ from within Vala.

Vala is a statically typed language and will remain like that; so it's
just a shortcut, it's not planned to support runtime variant types.

var may be used in variable declarations where the type is obvious but
e.g. you don't want to write the type names - possibly including generic
type arguments - twice when creating a new object instance. I don't
recommend usin var for basic types like int or string.

There is nothing speaking against code completion for var variables, in
principle; it will certainly need a more sophisticated code model but
libvala might be able to provide that.

Looks quite nice, thanks.
