This Hacker News thread discusses Web Embeddable Common Lisp (wecl), a project aiming to bring Common Lisp to the web via WASM. The discussion touches on its current status, performance, and potential. The author, jackdaniel, mentions a grant for improving browser integration and WASI porting. Commenters inquire about SLIME support (potentially addressed via websockets), compare it to other WASM-based languages like Guile Scheme and Gambit Scheme, and discuss the possibility of implementing Maxima. A point of debate is the speed compared to SBCL, acknowledged by the author as due to a simple bytecode compiler. The viability of WASM as a target for REPL-driven programming is questioned, with answers highlighting the dynamic nature of WASM module generation. WAForth is mentioned as a good example of this. The possibility of direct UI updates from Lisp code within the browser is also discussed.
