Ok sorry I thought the question was referred to me :) There are many pub/sub modules for go but I made this one because I was missing in some case the asynchronous callbacks that I can use with other languages ( node for example ) but in a really simple way without too many ceremony (probably I am too stupid for other solutions) and also with the benefit of using the async go routines that IMHO are an advantage and not cons like someone else pointed out (performance tests are still needed here)
