Re: [racket-users] strange typed-racket contract error
I also get a similar error message with this: #lang racket/base (require typed/racket/base) (require/typed racket/math [pi Real]) . . ../../Applications/Racket/April-24/Racket v6.2.0.2/collects/racket/contract/private/blame.rkt:143:0: pi: broke its contract promised: #f produced: 3.141592653589793 in: #f contract from: (interface for pi) blaming: (interface for pi) (assuming the contract is correct) at: unsaved-editor:3.28 So should require/typed produce a syntax error about being used in an untyped context?

Re: [racket-users] strange typed-racket contract error
This doesn’t happen if I change the language of the submodule to typed/racket/base, so I’m guessing this is because require/typed isn’t meant to be used in untyped code. So should require/typed produce a syntax error when it’s used in untyped code like this?

Re: [racket-users] strange typed-racket contract error
This appears to be a bug -- my guess is that the contract isn't actually generated, and thus turns into `#f` -- that's what `require/typed` expands to, before TR inserts the real contract.

The definitions for generated contracts default to #f. Can you submit this as a TR bug?
