goroutines are Erlang-like. Erlang doesn't have 'exceptions' though. In Erlang, if a process crashes (simulated or unexpectedly) it implicitly sends a specific message to it's parent. In Go you can emulate this by just checking for return values of stuff you do in the goroutine and send a similar message if it fails.

The fact that Go is in early development here and I'd say this both could and will be improved in the future.
