(Thanks to Claire Alvis.) Since programs are rarely intended to produce #<undefined>, raising an exception provides earlier and better feedback to programmer. Module-level variables have always triggered an exception when used too early, and this change makes local bindings --- including fields within a class --- behave the same. This is a backward-incompatible change to Racket. Aside from exposing a few bugs, the change mainly affects programs that include (define undefined (letrec ([x x]) x)) to obtain the #<undefined> value. There is now no #<undefined> value in the old sense, but the `racket/undefined` library (which was introduced in the previous release) provides `undefined` for use in place of the pattern above when an "undefined" value is still needed. ---------------------------------------------------------------------- _________________________ Racket Developers list: http://lists.racket-lang.org/dev
