What I would do here is something like:

1. standardize on JSON as the internal representation, and

2. write a simple (<1kloc) Python-based compiler that takes human-friendly, Pythonic syntax and transforms it into that JSON, based on operator overloading.

So you would write something like:

    from factgraph import Max, Dollar # or just import *
    tentative_tax_net_nonrefundable_credits = Max(Dollar(0), total_tentative_tax - total_nonrefundable_credits)

    def __sub__(self, other):
    return SubtractNode(minuent=self, subtrachents=[other])

The US has no single national photo + chip ID card that is available to everybody, for free, including illegal and semi-illegal immigrants and homeless people with no access to their birth certificate and such.

It's completely crazy to me that you can be "out of status" with the USCIS and still get a social security card and a bank account, for example.

I just append "explain", or start with "tell me."

So instead of:

"Why is foo str|None and not str"

I'd do:

"tell me why foo is str|None and not str"

or

"Why is foo str|None and not str, explain"

Which is usually good enough.

If you're asking this kind of question, the answer probably deserves to be a code comment.
