Earlier quoted context omitted.
do you think elisp will work for this book? or would one need to implement unique common lisp features in elisp? or will elisp just be too slow
most of it should work in elisp, note that elisp and common lisp have different semantics for IF. you might find some variances later on. also elisp doesn’t have as nice a debugging environment as SLIME so I’d honestly recommend just setting up common lisp
Are you referring to the IF expression or something different?
