Go is compiled/statistically typed language. it'll definitely be faster in most cases than dynamically typed language (where perl/python will have to perform some type checking at run-time) Perl will definitely be more flexible. e.g in Perl, you could use a module (like Moose) to have declarative-feel OO while in Go, you got half-baked OO and lack of generic (despite being static type language). Goroutine doesn't auto-magically make concurrency safe/nor avoid races or dead-lock. In my opinion, golang is oversold.
