Hi,

Yes definitely file a bug for that.

If you ever use valac and get any error or warning messages, there is
most likely a bug in the valac codegen.

And if you aren't sure whether something is a bug, file it anyway,
since the maintainers will typically pay much more attention to bug
reports than the mailing list. :) If it turns out to not be a bug, the
maintainers will be able to easily identify that and close it, no harm
done :).

Cheers,

The reason there's a problem is that GRegex does not utilize GObject, which supports giving GTypes to enumerations, thus allowing them to be used as properties.

To fix this, Vala would need to generate the GEnum boilerplate code somewhere. You can do this yourself with glib-mkenums.
