Nice! That works for me. However, may I clarify/confirm usage?
If I put the cursor on the closing parenthesis of the expression, then the
first command just copies it to the REPL, the second copies and then
evaluates it. Is this correct usage?

Well, like I said earlier, in practice, you may have to modify the
expression before you can run it.
Personally, I think SLIME could do with a command like this.
Thanks for the nice piece of code, Stelian.
