Half the time a new language gets introduced here and I spend 15 minutes hunting for some page somewhere on the site that deigns to share what the code looks like.
Agree with the point, but Vala is pretty old (relatively speaking). It's been around for a while and the whole idea is to have a GTK/GObject-focused C-family language. Last I looked it was a C transpiler and may still be.
I like to use Cheese, the nice little webcam app, to test a webcam when I first set it up or just take a selfie, even when I'm not on GNOME. That's a Vala application :)
