For that matter, is there any good reason to restrict the syntax of "require"
at ALL in student languages? I mean, it's not like a student is going to
accidentally stumble on
(require (prefix-in foo: (only-in bar/snark boojum glerbix)))
And even if they do, explaining that would be easier than explaining
(require (planet "main.rkt" ("clements" "rsound.plt 2 6")))
.
A related feature request, which I've put in at least once or twice: allow
students to use "require" on their OWN files, perhaps by putting an implicit
"provide all-defined-out" on any file in a student language. This is easy to
motivate: I frequently give an assignment that benefits from re-using a
function from a previous assignment. It seems to me quite reasonable for a
student to write
; Homework 6
(require "homework5.rkt")
...
; use functions defined in homework 5
Or perhaps even
; Homework 6
(require (prefix-in hw5: "homework5.rkt"))
...
; use functions defined in homework 5, as prefixed
