Indeed.

What's less fun is when you have to back the change out, or when you
want to incrementally comment out a nested sexp.  It works well, but
it's a wee bit fiddly.

For example, given:

(foo (bar ...
          (baz ...)))

With `comment-dwim', I might get something like:

(foo ;; (bar ...
     ;;      ;; (baz ...)
     ;;      )
     )

This would be more convenient:

(foo #;(bar ...
          #;(baz ...)))
