Yes! That's a great idea Peter, we always underestimate/forget what  
can be done with the scripting capabilities of ghci.
In this case, Ralph can get what he wants (modulo core dumps) with:

*Main> :def listStep (\_ -> return ":list\n :step")
*Main> :set stop :listStep
*Main> :step <your function call here>
