Hi,
the command `eval-last-sexp' has a very useful feature: Having point at
a symbol (or a sexp) that is enclosed in `...' (think of the manual or
docstrings), the sorrounded quotes are ignored so that evaluation of it
works.
OTOH, `pp-eval-last-sexp' doesn't have this feature. I think it really
really should, I can't see any disadvantage. As a workaround, the
following works well for me:
(fset #'pp-last-sexp (symbol-function 'preceding-sexp))
Besides: IMHO it's a pity that pp.el is not described in any manual (or
is it? - didn't find something).
At least, the header of pp.el should describe how to use it. E.g. just
tell the user to do
(global-set-key [?\C-x ?\C-e] 'pp-eval-last-sexp)
(global-set-key [?\M-:] 'pp-eval-expression)
or something like that.
Thanks,
Michael.

Makes sense to me -- you don't happen to have a patch for this? :-)

Are there any cases where using the pp version of eval-last-sexp (etc)
would be awkward? If not, adding a comment like that (and mentioning
the pp commands in the manual) sounds like a good idea.
