'bash'ing vars (dumping same)

Can you echo all the variables that are not exported with a single command in bash?

Good question!
The best I can think of is:

(env | sed 's/^\([^=]*\)=.*/\1/' ; compgen -v) | sort | uniq -u

However, this does not echo the values of the var's though, it only lists their names.

"compgen -v" lists the names of all var's, the rest of the commandline above serves to get rid of the exported ones.
