It was suboptimal in that more operations should be allowed now (such as accessing elements of a mutable vector provided under the type `Any`). However, some of the errors that this has caused in practice make me think that the previous implementation was wrong as well, since some of the programs that broke shouldn't have worked. > On Oct 28, 2012, at 9:58 AM, Sam Tobin-Hochstadt <sa...@ccs.neu.edu> wrote: > >> On Wed, Oct 24, 2012 at 8:29 PM, Ryan Culpepper <r...@cs.utah.edu> wrote: >>> >>> samth: >>> - type->contract fixes/changes (9e1cf579a4, 962f2472e1) >>> - add #:opaque and #:struct to require/typed (9054d0db7d) >> >> Typed Racket now handles higher-order values provided to untyped >> modules under the type `Any` differently.
