The thing is, given Go's compilation speed, little utilities will compile so fast that you'll barely notice it (on any decently powerful machine), and on the other side there's the overhead of starting up the Python or Perl interpreter.
There's also the "go run" command, so you don't even have to give two separate commands (compile and run).

The command "go run filename.go" compiles the specified Go source file and then runs the resulting binary (assuming no compile-time errors, of course).
