This patch addresses two issues with `typed/racket/class`: 1. For multiple private fields declared with `define-values`, type information does not propagate from the values produced by the initialization expression to the declared fields. This breaks soundness of private fields: A field can be annotated with a type that does not contain the field's initial value. This was resolved by keeping a table of temporary bindings introduced in the expansion of the initializer along with their types. The field setter's type is then checked against that of the corresponding temporary. 2. The class body typechecker assumes that the `expr` of a `define-values` clause will expand to a bare `(values vs ...)`. This was resolved by generalizing the template for matching an expanded `define-values` initializer and extracting the type information from the `expr` instead of each element in `(vs ...)`. |

Installation
Typed Racket is bundled in the default Racket distribution, which you can download from Racket's download page.
You can also manually install it from the main package catalog with the following command:
raco pkg install typed-racket
