CLRHack: Tail Recursion

Tail-Call Handling in CLRHack I decided to make proper tail recursion a fundamental requirement in CLRHack. This prevents stack overflow errors during standard recursive patterns and ensures the runtime remains stable regardless of recursion depth. Technically, Common Lisp isn't required to be tail recursive, but I want mine to be. 1. Tail Position Identification The compiler performs a structural analysis of the Abstract Syntax Tree (AST) to identify "tail positions." An expression is in a tail position if its value is the final result of the function, meaning no further work remains to be done in the current frame after the call returns. The generate-step2 walker propagates a tail-p flag through the following logic: Functions/Lambdas: The final expression in the body is in the tail position. Conditionals (IF): Both the "then" and "else" branches are in the tail position. Sequences (PROGN/LET): Only the very last form in the sequence is in the tail position. Blocks: The last form of…
