The `rhombus` executable automatically caches compilation by default, like using `-y` with `racket`. There's one significant drawback, which is that startup time can be significantly slower, so `-u` is available...

@tonyg I'm not sure what you have in mind. What would be an example of that happening?

The `pict` library for Rhombus is in some ways a unification of `pict` and `2htdp/image`, in that it takes some better ideas from the latter while building on the former....

Thanks! Should I squash these commits to merge, to keep them separate?

The note in #656 probably should have gone here.

Fixed in v8.17.
