Some of the interface is intuitive and great, but in MCL I could use (local #) to the Listener in a break to access and then manipulate values.  The documentation suggests that I should be able to get values of arguments and of local variables, but it doesn't work consistently. I've attached a copy of the top of a backtrace window.

Here's what I get:
? (defun foo (a) (let ((a (+ 10 a))) (break) a))
FOO
? (foo 10)
