$vau vs fexprs
As far as I understand it, $vau expressions are not exactly fexprs, though they are related. It seems fexprs get the actual symbolic representation of an expression, but $vau "operatives" get opaque expression objects. John Shutt's thesis "Fexprs as the basis of Lisp function application" discusses the theoretical issues with fexprs and how $vau improves them. I'm just leaving this here in case someone who actually knows about this might address either the article or this comment. Kmill (talk) 20:09, 27 August 2021 (UTC)
