Or simply run python.exe from another console process that keeps the
console alive (it's reference counted), which is typically cmd.exe or
powershell.exe. Or have the script spawn a process that keeps the
console alive (e.g. subprocess.Popen('cmd')). Or configure .py files
to use the py.exe launcher and change the shebang to `#!python3 -i`
when testing a script, which runs the REPL after the script
terminates.
