I'm a fan of Go's "go run". For example, you can do:

  go run main.go

or:

  go run ./cmd/server

When invoked this way, Go compiles your code behind the scenes, but you don't have to create a binary.

This means Go lends itself pretty well to ad-hoc scripting or writing small script-like tools.

Unfortunately, Go doesn't support shebang lines, but with gorun [1] you can:

    #!/usr/bin/env gorun

    package main

    func main() {
      println("Hello world!")
    }
