I hate to followup to my own posting, but: 1. I appologise for all the CR characters at the end of each line. 2. I realized I made a mistake. The original posting: >>xlapply, xlevform and sendmsg will issue an error if they encounter a >>s_macro CLOSURE. This is presumably because all macros are expanded >>by xleval.c:xlclose when it builds a closure. >>Neither xlapply nor sendmsg will handle FSUBRs. This is presumably >>a minor bug, left due to the difficulty of keeping arguments >>unevaluated to that point. ? Corrected reply: Common Lisp does not allow APPLYing a macro or special form (FSUBR). This is based on the evaluation model. Since SEND is a subr, all of its arguments are already evaluated so it is already too late to have macro or fsubr methods.
