Sure you COULD do that, but app is so cool, I just like the way it looks.
Also, Sam, I've thought more about this and I've definitely made the
assumption that the "and" pattern evaluates left to right. For
example, in the bidirectional matchers that are underneath the URL
dispatch library, I assum
Why wouldn't you write that match like this:
(match ..
[`(+ ,lhs ,rhs) (make-plus (parse lhs) (parse rhs))]
[`(fun (,(? symbol arg) ...) ,body) (make-fun arg (parse body))])

Okay. I think it is strange, but feel free to do that and revert my
change. Apologies for the confusion.
The use case I was actually doing was like this:
[(list '+ (app parse lhs) (app parse rhs))
...]
[(list 'fun (list (? symbol? arg) ...) (app parse body))
...]
And when you gave it a '(fun (

This is not a bug. `match' makes no guarantee about the order in
which it checks elements of the pattern.

I've tracked the problem down to reorder-columns.
There are no test cases anywhere for reorder-columns and the code has
no comments on its purpose, so I'm not sure how to fix it.
It seems that the presence of Null and Dummy in the parse of the

I found an interesting error in racket/match in my 330 class this afternoon.
(test-case "app pattern"
(check = 4 (match 3 [(app add1 y) y])))
(test-case "app pattern (step 1)"
(check = 2 (match (list 1 3)
[(list 0 (app add1 y)) y]
YESSS! And since I'm on the ball today, there should be a "porting" doc
page and everything.
I'm seriously looking forward to helping you port the science collection
and getting your reactions to the new library.

For that matter, is there any good reason to restrict the syntax of "require"

There aren't any porting docs, and that would be really helpful. So yes,
please!
These 'plot' doc pages are finished:
- PLoT: Graph Plotting (main page)
- Introduction
- 2D Plot Procedures
- 3D Plot Procedures
- Compatibility Module
Reading over the finished pages should help you a lot.

I believe that this is something that's long been asked for and
amounts to lifting a restriction in the current teaching language
implementation (and then presumably auditing the error messages).

Thanks, Neil!
Is there some docs to help people port?
If not, would it be helpful for me to read over the plot and
plot/compat library and try to put such docs together?

I've just pushed the new 'plot' library.
Eli and I both forgot that the new 'plot' still needs the old libfit,
and removed it along with libplplot. I just added libfit back (the
sources are in "src/fit" now instead of "src/plot/fit") along with the
proper configure, Makefile.in, and get-libs.r
Yes, please!

I'm using the rsound planet package in beginning student languages, and
requiring them to type
(require (planet "main.rkt" ("clements" "rsound.plt 2 6")))
at the top of every file is a bit painful.
