pp-eval-expression's interactive spec is this:
(interactive "xPp-eval: ")
eval-expression's interactive spec is this:
(interactive
(list (read-from-minibuffer "Eval: "
nil read-expression-map t
'read-expression-history)
current-prefix-arg))
pp-eval-expression should, like eval-expression, use
read-expression-history. Either it should use a similar interactive
spec, or, perhaps, the `x' flag should use the read-expression-history
generally.
I suspect that a common use case is to first use M-:, and then, if the
result is very long, to repeat the evaluation using
pp-eval-expression. Users should be able to retrieve the previous
expression using M-p. (The *Messages* buffer truncates result values,
BTW, so users can't always retrieve it from there, and that is more
roundabout, anyway.)
I personally bind M-: to pp-eval-expression. I'm not sure why this
is not done by default, but there is probably some good reason.
