I would very much like to be able to control the environment that miniMAL instructions can execute in. The ability to set miniMAL({}) does not prevent access to the whole of JS, including the dangerous global function eval.

Being able to have control, or prevent any crazy stuff potentially executing from a miniMAL program, would enable this library to be used for user customizable dynamic rules, like access rules, event rules etc, that can be stored as JSON in a database.

I guess that some second argument to miniMAL() preventing just the "js" feature, would do most of the trick? (But there would probably be a more general way to do it)

I only get:

TypeError: Object prototype may only be an Object or null: undefined

when running node test.js.
Where test.js is:

const miniMAL = require('minimal-lisp');
const m = miniMAL();
m.eval(["+", 2, 3]);

Hello.

I'm trying to develop another implementation for miniMAL language
adding some more features, not using your original source code except unit tests.

Questions:

1. Is there any license or copyright as if miniMAL's langage SPECIFICATIONS?
   • Of course I know your miniMAL IMPLEMENTATION is distributed undef MPL 2.0.
2. Is there any limitations to publish my miniMAL implementation to NPM
   under MIT license?
3. Can I still call or name my implementation as `miniMAL' language?
   My implementation will not be small as your awesome code, but
   trying to pass most of unit tests (which are converted to Jest format).
4. Can I refer your web pages from my documents?

Regards,

Is there a good reason why modulus ("%") is not among the available operators?

Should it be, or is there an easy way around it?

Seems like it would be (reasonably) trivial to write a parser for Lisp code (that was Lisp-0 compliant anyhow) by a simple regex.

Someone on Hacker News mentioned this for python:

`def parse(s): return json.loads('['+re.sub('([")])\s*(["(])','\g<1>,\g<2>',re.sub('[^()\s]+','"\g<0>"',s)).replace('(','[').replace(')',']')+']')``

Seems like most of that should go 1-to-1 into a JSON regex (as naive as it is).

Just a thought....
