Alternative Approach

Use R as environment/system/interface
shell/command line
Then replace or augment language
- Compile R language to make it faster
- implement new language(s) to replace R
- allow user to specify language, e.g.
```
newLang1({
            expression_1
            expression_2
            ...
            expression_n
         })
```
  Use R syntax for commands to be interpreted in a different "interpreter"
- Allow any number of new languages.
Use R as the parser
- Good and Bad - but expedient
- like LISP - all same syntax calls - function calls
