lish [[--live] | [filename]]

You can use --live argument to make it evaluate as you type, or give a file to execute.

With the --live argument: As the shell input is auto-processed every second, be carefull to what you type in. This can lead to various errors and can make your filesystem messy if you don't handle it carefully.
