This is the bug -- there's no way to write the boxof-integer? predicate,

More generally, this is a case where you want some form of negation
(plus bounded polymorphism) in the type system, but that's not
something I know how to add straightforwardly to Typed Racket.

The errors are delayed in exactly the way that they are for the contract
'(-> none/c any/c)'. If you apply that contract to 'add1', it doesn't error
unless the resulting function is applied.

Typed Racket now handles higher-order values provided to untyped
modules under the type `Any` differently. Thi

make me think that the previous implementation was wrong as well,
since some of the programs that broke shouldn't have worked.

With my latest fix to handling of the `Any` type, the following small
program (also at https://gist.github.com/3991023) crashes drracket (I
can't provoke the bug with plain racket):
#lang racket/load
(module m typed/racket
(define: v : Any (exn "" (current-continuation-marks)))
(provide v))

Impressive!
I've looked over the docs, and while I have lots of comments that I'll post
later, I want to say that this is a very nice design, and hits exactly the
right spot. I'm really excited about what this holds for Racket.

Yes, you should add an entry to typed-racket/base-env/base-special-env
for `check-em`. Note that you'll have to specify which module
