Re: [plt-scheme] Re: webserver and print-struct

[Robert Bruce Findler <robby@cs.rice.edu>]

DrScheme sets up a special inspector for the read eval print loop.
Whenever a value is printed by the repl, the contents of the structure
are shown. If you were to `display' the value or something like that,
you'd not be able to see the contents of the struct.

I think that you've found the most workable solution, by adding
`make-inspector' to your struct definitions.
