> Go makes concurrency easy to get right. I haven't seen any other language get this so right since Erlang. I don't understand this: You claim you've used Haskell? Haskell beats Go's concurrency out of the water. Not to mention conciseness...
And space leakiness...
None of my Haskell programs have any space leaks.
While go makes a lot of correctness bugs really easy to accidentally make, Haskell does make a certain class of leak easier to maker. I'd personally take a correct program that leaks in some scenario over an incorrect one that does the wrong thing.
