Re: [Vala] OpenMP Support

Hi Adrià,

I think not only that, but also to recognize when this can be done and
where cannot. But I think that using most Glib types can be done if the
data structures are thread safe something I'm not aware of it. I suppose
it's not easy. But can be a great win to put vala at the same level of
scala and rust.

Best regards,
