remokasu/stacker: command-line RPN calculator with an RPN-based scripting language (on PyPI)
Stacker is a command-line calculator that uses reverse Polish notation (RPN) for mathematical calculations and features an RPN-based scripting language. - remokasu/stacker

how does that compare to Hy besides being more domain specific and the order of operations (prefix vs suffix notation)?
I've never used Hy. Does it offer any concatenative-style interaction?
it's uses standard lispy operator-operands order see https://learnxinyminutes.com/docs/hy
So it looks like a totally different data flow style, and (I think) geared toward writing then running programs, whereas Stacker is more for interactive stack-oriented calculator tasks.
lisps are very repl-driven too
I'd say an important part of this calculator's interaction model is doing something, getting a result, then doing something else to that result. That's not too bad in the regular Python interpreter either.
For example, in Python:
>>> 5 5 >>> 4 + _ 9 >>> 2 * _ 18In Stacker:
>>> 5 [5] >>> 4 + [9] >>> 2 * [18]Does Hy have something like the Python interpreter's
_?
