I persevered following the "Learn" link. Then went to the Github page. https://github.com/AvailLang/Avail/blob/master/distro/src/ex...

Not impressed tbh.

    Module "Hello World"
    Uses
	"Avail"
    Extends
	"Avail" =
	(
		"keyword lexer"
	)
    Entries "Greet"
    Body

    Method "Greet" is [ Print: "Hello, world!\n"; ];
