How using .query stack in REST API?

[Amm0]

For some reason, I have never encountered such an approach with a stack to organizing logical calculations before. Really liked its simplicity of implementation, will use it in my projects when need to be able to set the behavior of an object by user in settings.

I like esoteric programming languages. RouterOS script is in that category. Someone at Mikrotik must have read Ken Iverson books (creator of array languages like APL, J) & be an expert at lex/yacc is all I know. But if you like “.query stack”, you’d like https://www.uiua.org - dozen of primitives to operate on a stack expressed as unicode symbols.
