Could you build this?

No Implementing an ANSI-compliant Common Lisp runtime and interpreter (including CLOS, condition handling, and complex macros) is a multi-year specialized language runtime project.

What it would actually take: A full ANSI Common Lisp implementation requires writing a memory-managed runtime engine (often in C or C++) featuring precise garbage collection, dynamic object typing, multiple return values, lexical closures, and the Common Lisp Object System (CLOS) with generic functions and dynamic method dispatch. Meeting the extensive ANSI X3.226-1994 standard requires navigating thousands of edge cases, reader macros, and complex compiler/macroexpansion mechanics. This necessitates deep systems architecture and language design expertise.
