One does not exclude the other?

Anyway, I just replied on what you wrote:

If you just pretty print it in a separate buffer, it is almost as good as in a
tooltip, but can be a bit distracting depending on how Emacs chose to split
buffer. Didn't have time to build and test your code, my build is like two weeks
old or so.

Examining the value of a variable while debugging?

For me it is a normal thing. I press 'e' and then type the name of a variable,
or I sometimes move curser at the end of var/expression and press C-x C-e. Would
be nice if edebug instrumented code with help-echo to display values, or even
the doc together with the value, similar as in help buffer but in a
tooltip. That way we could just move the pointer over symbols and quickly see
values/docs, instead of pressing e and typing.
