Racket now supports 64-bit Windows (Vista and up).
To build for 64-bit Windows using VS 2008:
1. Use
vcvarsall x64
to configure your environment for a 64-bit build, where
vcvarsall.bat is supplied by Visual Studio in the VC
subdirectory.
2. Run
build.bat
These contracts are not thrown at dynamic places. The contract is always
at the module boundary/etc, but its meaning if affected by the dynamic
context of the particular boundary crossing. [1]
I'm been thinking about why I want to use contracts for this purpose.
The alternative is to put an
Let's be clear here: our inability to enforce projectionness is in no
way condoning the two coercianlike contracts that you have now
written.
That said, the only value I see to contracts that only signal errors
(or do nothing) is that programmers know what to expect from them. The
downsides you
Yes, since I am allowing users to customize the coercion behavior, I could
either have them provide two functions: a coercion-applies? function and a
coercion function; OR I could have them just provide the coercion function
and I will check the answer and re-run it inside of the function body.
(This is a SE sermon, general but hopefully not opaque as Matthew and Robby
think my emails often are:
Separating the contract from the functionality of a function/method/etc is a
matter of stating the interface clearly and as such a matter of documentation.
So use contracts for that

The interoperability comment just hit me. What we might be discovering is
basically Jacob's thesis in practice. It isn't so much contracts+X that we're
looking at to implement interoperability, but contracts = interop-stuff +
blame-mechnism + possibly-more. Jay is trying to reuse the first
That's why dynamic/c has a pre/c and post/c. Before it uses the user's
contract, it applies pre/c. After it applies post/c. This ensures that the
user's contract actually coerces to a response?

I believe that this line of discussion is on target. Interoperability is
between boundaries. Our contract system is really good at finding and
interposing between these boundaries, so it is natural to use it in that
way. There is a notion of blame in interoperability too, when the cast
fails.
Jay
Right. (My contracts+X comment was a view from underneath comment. I
was thinking that the documentation system, for example, might have to
change to extract the contract part of these new things and show that
to the user since I expect the coercion part to be something that is
an internal
Maybe dynamic/c isn't clear enough... its definition is pretty short:
(define (dynamic/c pre parameter post)
(define pre-ctc (coerce-contract 'pre pre))
(define post-ctc (coerce-contract 'post post))

Also: is this really supposed to be a parameter? That is, do you use

The provider of the coercion should be blamed, but that is not possible [I

This isn't quite right.
Yes, the idea is that you can set the parameter inside your servlet and that
will effect the thread-cell for your servlet thread. Or, you can
parameterize before you serve/servlet or send/suspend for a sub-component of
your servlet with a different response representation
