Nu map from functional languages

The idea behind this table is to help you understand how Nu built-ins and plug-ins relate to functional languages. We've tried to produce a map of all the Nu commands and what their equivalents are in other languages. Contributions are welcome.

Note: this table assumes Nu 0.43 or later.
