My guess would be that maru's quasiquote is somewhat buggy. Quasiquote is really difficult to implement right. I tried once, and failed to optimize the expansion in a way that handles ,@,@ then eventually fell back to closely following the reference implementation http://cliki.net/fare-quasiquote Also note that the semantics of quasiquote is underspecified in Common Lisp, as to how it interacts with the special syntaxes of various other data structure constructors (e.g. what is `#3(1 ,@'(2 3)) ? If you have other builtin or user-defined structure constructor syntaxes, how does it interact with quasiquoting?). I am not sure how Scheme or Clojure resolve the issue... probably not in a well-designed way. That's an area where indeed maru could improve on CL, by e.g. specifying a meta-quasiquote protocol for how quoting interacts with user-defined syntax. If you're interested, there's experimentation and design to do, and probably a paper to publish. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org "Computer programming is omnipotence without omniscience." — Prospero, as cited by Eliezer Yudkowsky _______________________________________________ fonc mailing list fonc@vpri.org http://vpri.org/mailman/listinfo/fonc
