What about R? It would be extremely easy to do these calculations and output in 
an appropriate form.

Subject: [lp-ca-on] tax software design considerations

Income tax software has to perform spread-sheet like calculations which
I believe are more generically known as reactive programming.
It would be nice to feed the calculation rules into the engine as data
which means either a compile step or a reflexive language.
I've written my tax calculations in XSLT 2.0 which can do reactive
programming via global variables. However it is not reflexive as of 2.0.
This looks to be available in XSLT version 3.0
https://www.w3.org/TR/xslt-30/#element-evaluate. I'm not sure if there
is a libre version of XSLT 3.0.
Meanwhile I've hardcoded the calculation rules in the XSLT 2.0 code.

There is most likely a better way. Javascript? Lisp?
