The contracts I wrote in the patch do reflect this via the
`stx-pair?` predicate, FYI.
By the way, the definition of a syntax pair in the documentation is

Is that really so misleading though? There is already precedent for

Just realized after I sent it that I'd change two things in the patch:
* `syntax-null?`, `syntax-pair?`, `syntax-list?` would be defined
using `procedure-rename`
place `syntax/stx` for most users and provide both better
error messages and identifiers that follow standard Racket naming
convention.
I've attached a patch that implements this. Any comments?

Yes, the changes we made to racket/dict will work with hashes, vectors,

Hi all,
Racket currently provides several generic extensible data structure APIs
such as dictionaries, sequences, streams, and so on. Unfortunately, each
data structure currently has its own extension API, but no consistent
convention exists: some APIs use lists of methods, some use vectors,

Hi all,
Recently I have been adding class contracts to parts of the GUI system.
In tandem, I've also added a new feature to `class/c` that allows a
contract to be opaque, which means that the contract requires that *all*
public methods & fields in the contracted class are themselves
contracted.

Hi all,
Stevie and I have been hacking on an addition to the class system that

used in the codebase, so the idea here is to make this a language feature
