When attempting to run the following snippet using Nteract and the latest version of GopherNotes, I get the following error: ```go import "crypto/hmac" import "crypto/sha1" h := hmac.New(sha1.New, []byte("bananarama")) _, _ = h.Write([]byte("some data")) h.Sum(nil) ``` ``` repl.go:5:8: not a package: "h" in h.Write <*ast.SelectorExpr> ``` However, if I try to compile and run the following using the `go run` command, I get no error, and it runs without a hitch: ```go package main import "crypto/hmac" import "crypto/sha1" func main() { h := hmac.New(sha1.New, []byte("bananarama")) _, _ = h.Write([]byte("some data")) h.Sum(nil) } ```
