Hi all,
Many racket collections define some modules in a subdirectory named

convention and
For most functions, I don't think it should be documented differently.
(All ...) is a good point, but it's something we should fix for
functions with plain old contracts as well.

The key distinction is setting parameters at compile time (which is when
include happens) and run time (which is what Rüdiger did). I have sent along an
explanation of how units may solve his problem in a better way. -- Matthias

Actually numbers are allowed, but not all numbers. If you look at
http://docs.racket-lang.org/xml/index.html?q=xexpression#(def._((lib._xml/main..rkt)._valid-char~3f))
It tells you which numbers are allowed, and 2 is not.
I'll change the error message to say "valid numeric entity" rather than

Sam,
Is there a reason you think there should not be Scribble forms for
typed code/APIs? I think it would be good to communicate its
typed-ness and have support for things like For Alls, (How are you
going to communicate for-all-ness with pretend contracts?)

Hi!
In DrRacket version 5.02 this x-expression
(validate-xexpr '(add x 2))
is legal. In version 5.2 I get the error message
Expected a string, symbol, number, comment, processing instruction, or list,
given 2
Can anyone explain this to me?
