-;; also make `zap-up-to-char' available
+;; Is a binding for `zap-up-to-char' needed in addition to one for
+;; `zap-to-char'?  If you don't need to insert any text before the target
+;; char, then M-z CHAR CHAR is equivalent to using `zap-up-to-char' with CHAR,
+;; and is easy to type.  If you do need to insert, you can just M-z CHAR, type
+;; or yank, and then type CHAR again to conclude.  By contrast, replacing use
+;; of `zap-to-char' with `zap-up-to-char' is not so easy, as you might need to
+;; switch from typing M-z to typing C-d, for example.
+;;
+;; At the very least this demonstrates that `zap-to-char' more deserves to be
+;; on an easy-to-strike key than does `zap-up-to-char'.  So for now, make the
+;; other command available on a less valuable key.
+;;
+;; Hmm, might be good to add `paredit-zap-to-char' which doesn't actually
+;; delete some delimiters.
