Scheme

I would like code like this:

(define-struct thing (a b c))
(define th (make-thing 1 2 3))

to print something like this:

(make-thing 1 2 3)

when I type "th" into either the DrScheme or MzScheme repl. I am using the language "pretty big" in DrScheme with output style set to "constructor". This is what I get in DrScheme:

(make-thing ...)

(i literally get the three dots)

In MzScheme:

#<thing>
