[racket] Evaluating expression in Dr Racket debugger. Maybe a feature request??

Hi All,

I am evaluating/using racket and DrRacket for my daily work and so far am
quite impressed. Maybe I am being bit greedy or maybe this is something I
have overlooked, :-) . I was wondering if there a facility to evaluate
expression while in debugging mode. For example say I am debugging the
following function below and the 'debugger stepper' is about to execute (+
a b). What I would like to do is evaluate an ad hoc racket expression - for
example (- a b) and get the result of it. Here is the code

(define (dosomething a b)
  (* (+ a b)  ;; the debugger is here
     (* a a)
     (* b b)))

For analogy the functionality that I explained is similar to the immediate
window functionality of Visual Studio.

Is this possible in racket? I have attached a screenshot of the debugger.

Many Thanks
