> The real essence of Go channels is their ability to participate in the built-in select keyword.

Select is similar to a function in plan 9's threading library[1] (which is part of the Go lineage) called alt(). To use it you stick it in a switch like so: switch(alt(alts)){}. Select{} is syntactic sugar for some alt like functionality. Of course the programmer is responsible for setting up the alt structure and the channels it contains. Overall its a great library and I love working with thread(2).

See this wonderful article on Go' history in code for comparisons between Go, Limbo, Plan 9 C and Alef: https://seh.dev/go-legacy/
