This gets the GType of Foo, instantiates it by increasing the ref count,
casts it to EnumClass and then uses the n_values field.

If someone was to add syntax support for this for both EnumClass and
FlagsClass, what would be the best way for this to look?

a) Explicit instantiation of the Foo EnumClass:

var a = new Foo ();
print ("%i", a.n_values);

b) Implicit access to EnumClass methods and fields:
print ("%i", Foo.v_values);



Opinions anyone?
