As the author of a JS-to-OCaml compiler [1], I must admit that Poe’s Law applies here [2]:
“Without a clear indicator of the author’s intent, any parodic or sarcastic expression of extreme views can be mistaken by some readers for a sincere expression of those views.”
Cool. Recursion in python is common bottleneck in competitive programming. Will give it a try. I created a similar tool for recursion [1]. But ended with rewriting AST and emulating stack. Pros - no need for accumulator, cons - almost unusable in real world.
