I really wish Go's select had guard clauses. The need to nil channels feels like a hack. However I haven't actually had much need for them but haven't written many things that would need them.

I do miss PAR's synchronization semantics, which Go programmers know as the "sync.WaitGroup" idiom. Given the number of times I see Go developers asking about synchronizing goroutine termination perhaps having some form of concurrent control structure atop 'go' could help. Or maybe not - they'd just start asking about their inability to terminate :) At least PAR is easy enough to simulate (I wrote myself a little 'par' package to hide the WaitGroup manipulations with functions/closures as the [CSP] process bodies).
