I have just added a WG1 ticket to require this in R7RS. > I have no quoting in my example clauses. Read it as follows: No, but case implicitly quotes its arguments, which makes it impossible (or rather useless) for them to be quasiquotations. > (case 'b > ((`,a) (list a))) ; explicate quasiquote That still won't work. (` ,a) is just (quasiquote (unquote a)), and in the context of a case key means "either the symbol quasiquote, or the list (unquote a which is eqv? to the one in the code". > I hope this WG shall not try make it more complex and large that it > needs to be.
