Re: Programs writing backquote
I'd like to second the proposal that Common LISP backquote "`" be
explicitly defined as expanding into a macro, and that ",", ",@", and
",." expand similarly into s-expression forms. This makes backquote
more accessible to programs. The point has been made that if "`"
expands into a LISP macro invokation, a conventional interpreter will
run the code relatively slowly. This kind of objection of course
applies to use of macros in general, and I don't think we usually let
it stop us from defining macros where they are useful.
