I'm thinking about writing up a CDR on #;-style comments.

But it's not unproductive. Now we know that it should be specified as equivalent to #-(and), that assuming it's CDR-10, that it can be used as:

#+cdr-10 #; #-cdr-10 #-(and) "commented out sexp"

oops, that'll break :-(

Ok, just joking, it would be used as:

#-cdr-10 (eval-when (:compile-toplevel :load-toplevel :execute) (error "please load CDR-10 before this source"))

#;"commented out sexp"

We've consider the cost to implementors (close to nul), but the cost to users (ie. programmers writing conforming code) is higher. Instead of the above I think I'll keep writing:

#-(and) "commented out sexp"
