I don't have a good sense for whether or not these items are worth being
mentioned, but here are summaries for them:

+ Typed Racket's type instantiation (`inst`) uses Any for omitted type

without breaking existing programs.

+ `for/fold` users can customize the final result of a loop's computation
using the `#:result` keyword.

Andrew
