Re: [Vala] New params for [ModuleInit]

[Nicolas Joseph <nicolas joseph valaide org>]

How ?! For this to work requires that the plugin registrar inherits from
TypeModule.

I quickly rewrote the example but it does not work:

$ valac --pkg=gmodule-2.0 --debug *.vala && ./main
> main.vala:10.1-10.41: warning: unable to chain up to private base
> constructor

And in a real application I have an error like:

g_type_plugin_* invalidly modified type

With the object creation.
