It uses Printer to transform an Object into a human readable form and sends it to $stdout.

Uses #puts method in the output to add a new line after sending each String representation created via Printer be sent to the output.

It is possible to override the preference for using $stdout by binding SYMBOL_OUT to a desired Object in the env given as a parameter to this method.

Parameters:

  • stuff (Object) —

    anything resulting from evaling a Campa expression

  • env (Context) —

    where SYMBOL_OUT will be searched to find an alternative to $stdout
