[plt-scheme] transition teaching languages - textual

You need to make the struct transparent. You do that by adding
(make-inspector):
(define-struct foo (bar baz) (make-inspector))
Now, choose the output syntax (in the language selection dialog box, click
show details). Write will not show the contents of structs, but quasiquote
style and constructor will. Current-print is to set the printer in code (I
think the default is write there). You should try out all three syntaxes,
and choose the one you like most. I like quasiquote, myself.
