Its aim is mainly to have vala without the quirks and limitations of
GObject. Vala with dova should be closer to Java and C# than now (but
it'll still be better ;-))

dova objects aren't compatible with GObject. I think there is a plan for
runtime bindings at some point but I don't know the details.

You mean GObject 3, right? I think it could be more like "glib 4" (I
think this was the "codename" used to refer to dova as it was still an
idea)

When you start using vala seriously (especially coming from Java/C#)
you'll find some difficulties related to how GObject works. Sometimes
vala works around them (e.g. constructor chaining-up), and sometimes it
cannot.

ATM, there is the vala command so you can do something like
vala --pkg=gtk+-2.0 myfile.vala
and have it compiled and run (tcc does something like this for C).
it should also work with '#!' in the beggining of the file.

Someone would have to play with dova enough to understand it and write
something to the wiki.
