I like the Go language for all of its efficiency and easy concurrency, but part of me can't help but think that they were dying to make some new syntax just for the sake of it.

That syntax was based on Oberon-2 (1991), given Robert Griesemer's presence on the team.

    PROCEDURE (q : Query) GroupBy*(field:  String): Query;
    BEGIN
     (* .... *)
    END GroupBy;
