I read a long time ago (I think it was on LWN, but I can't find the
article) about some tricks that are used in the linux kernel to mitigate
weaknesses of the C preprocessor. You wrap multiple statement macros in
do { } while(0), so that you don't have to think about whether you
need curly braces and it will absorb (and need) a semicolon, so that it
won't break your if-statements. You can read more about it here:

[racket-dev] Scribble does not complain when @tech{term} is used but not defined
Is there a subtle reason to not error? I've just seeded a file with a
lot of @tech{} uses and I was hoping to get a big list of errors as a
to-define list.
I looked at the code and found a commented-out error printing in the
HTML renderer. I think it would be great to re-enable it, perhaps with
a command line flag for the original objector?

[racket-dev] syntax property duplication
The following idiom duplicates the syntax properties on `stx': (define-syntax (m stx) (datum-syntax #'here 'id stx stx)) This is a problem for me because I use syntax properties to indicate polymorphic type instantiation. If an expression that's actually a macro using this idiom is instatiated, then Typed Racket tries to do the type instantiation twice, resulting in an error. See the below program, which fails. Should I expect that duplicate syntax properties are a natural result of expansion, and find some way to handle them? Or is there something else that should happen? #lang typed/racket (: id : (All (A) (A - A))) (define (id x) x) (define-syntax (m stx) (datum-syntax #'here 'id stx stx)) (inst m Integer) -- sam th sa...@ccs.neu.edu _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
Re: [racket-dev] getting oops, internal error messages when updating PLaneT packages
I think I found the bug. The problem I found was that, during the creation of the rss feed (the rss feed shows the recently added packages), the planet server was not being careful enough to guard against bad xexprs in package info.rkt files. Well, I didn't find any packages that would actually lead to that specific error which is a bit mysterious, but the error at that spot is consistent with you seeing the package actually be uploaded successfully (and the logfile that I can see), and is the only place where I see a call to that function (which is actually named write-xml/content) with non-checked input. So hopefully you won't see that error anymore. Thanks for the report.

I don't see anything obviously wrong with the packages, either. I'll have to look into this more later on but at least for the moment, I think that things are in shape.

I would prefer not to get an error so that I can compile modules independently.
