Phil,

I wouldn't become too attached to this command's implementation as it 
currently stands; rather just view it as a a glimpse of what is to 
come.  That command reports the expression's result's location which 
isn't sufficient; instead a walk of the expression tree that generates a 
list of all referenced locations is going to be needed.

I would define the frysk.proc. object interface that you require and 
expect the location tree walk code to generate that that information; 
rather than try to have frysk.proc directly access frysk.debuginfo.
