Not impressed tbh.

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

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

I'm pasting a link because I added on-hover popups explaining parts of the snippet, but here is the sample itself:

    Module "Hello World"
    Uses
        "Avail"
    Entries
        "Greet Router"
    Body

    Method "Greet Router" is [
        socket ::= a client socket;
        target ::= a socket address from <192, 168, 1, 1> and 80;
        http_request ::= "GET / HTTP/1.1\n\n"→code points;

        Connect socket to target;
        Write http_request to socket;
        resp_bytes ::= read at most 440 bytes from socket;

        Print: "Router says: " ++ resp_bytes→string ++ "\n";
    ];
