[plt-scheme] transition teaching languages - textual

hi,

I just started leaving the save haven of drschemes student languages so 
I probably miss something obvious, but I can't find a way to make the
display of structs as verbose as in the student languages - in the
interactions window it just gives me a

textual: #<struct:foo>

compared to
student: (make-foo bar baz ...)

is there a way to define this behaviour?


thanks,
Markus
