Yeah I love it when people start defining their own operators all over the place and give them all inscrutable names. "Dude just use the eggplant parm operator: <<=-=>>"
With languages like Scala I think its a clearer necessity that someone or some small group in an organization maintains a dominance of expertise or you have different groups that are only using the same language in name or facing overhead to keep in agreement where a lot of the best developers might be basically doing ambassador work.
