+Modifying this and @racket[current-trace-print-results] is useful to to get more

+For example, we can use @racketmodname[debug-scopes] to add scopes information

+In this example, we update the printers @racket[current-trace-print-args] and

+by storing the current printers (@racket[ctpa] and
+@racket[ctpr]) to cast syntax objects to datum using @racket[syntax->datum] and then
+pass the transformed arguments and results to the previous printer.
+When tracing, syntax arguments will be displayed without source location

+We must take care when modifying these parameters, especially when the

+argument/result of the traced identifier.
+This modification of @racket[current-trace-print-args] and
+@racket[current-trace-print-results] is an imperative update, and will affect all traced identifiers.
+This example assumes all arguments and results to @emph{all traced functions} will be syntax objects,
+which is the case only if you are only tracing syntax transformers.
+If used as-is, the above code could result in type errors when tracing both functions and syntax transformers.
+It would be better to use @racket[syntax->datum] only when the argument or result is actually a syntax
+object, for example, by defining @racket[maybe-syntax->datum] as follows.
