GoLang shebang for scripting

This is not really a shebang. Real one was rejected several times. But it still works:

• When you run ./main.go then it's evaluated as shell-script (sh or bash). Pretty version of it looks like this:

  go run <current file> <arguments>
  

• Go ignores first comment and executes as usually.

• Exit code is handled correctly.

Details

• //usr/bin/env go seeks for go binary and handles Go comment // correctly.
• $0 "$@" passess current file and arguments to binary.
• exit "$?" returns exit code.
