Is there any way for shared to check for whether a name was originally
assigned to an LHS and, if so, to re-use it? If I define
(define cities (shared ([PVD (make-city ... (list BOS ORD))] [BOS ...]
[ORD ...]) PVD))
and it prints as
(shared ((-0- (make-city "Providence" (list -3- -7-)))
(-11- (make-city "Boston" (list -3- -7- -16- -31-)))
...
it's really pretty hard to read! (What's worse is that changes to the
program change the assignment of -1-, -2-, etc., so even if I spent
some time memorizing that -1- is PVD, -11- is ORD, etc., after I make
a small change to my program, that memorized map is useless.)
