Can you suggest an idea for an esoteric JAP?

Question

Programming languages

Hello. Recently I decided to try my hand at writing a parser and I want to try any ideas for creating an eso programming language.

Answer 1

I can. Everything is a function that takes as input the execution context (1) + the text in front of itself as an argument and returns a dynamically typed value.
print sqr 2
here print will take "sqr 2" as input
Since sqr is also a function, print will pass the baton to it: "2"
sqr will return 4, which will print
