built in print() command returns nil

[Your-God]

Whenever you can print() in the command line; it adds an additional 'nil' line at the end.
I assume this is a bug because it doesn't happen to any user implemented commands.

This is expected because print returns nothing which is nil, the console prints the value the last expression evaluated to and print indeed evaluates to nil, just that its side effect is to print the text.
