I was told that when it comes to compare with polygon and image
rotating, polygon is much faster.

then why don't I change image into
Here's the simplest example I have on hand:

(It's a planet package too, pyramidstack)
But it also uses the Chipmunk physics library, so it may not be very
convenient to run

Everett has written a lot of code in it. I've encouraged him to send a
mail about his experience... hopefully he will soon ;)

Good of you to dogfood. I didn't really get turned on by alt-exp from
your previous post, but it's cool that you can express this!

That shouldn't be a problem.
Not for correctness, no. How about for time or memory efficiency?
I confused the crap out of Racket's GC by keeping
Here's mine, probably not a very good way to implement this, but it
works and it uses the alt-exp syntax I've been playing with recently.

Spec: define a case construct syntactically just like that of Racket.
In terms of semantics:

I anticipate we'd want some wrapper around formlets that check if the
code passes some predicate and it would be nice to have a predicate
language that could be compiled to JS for client-side validation and
ui updating.

I've read the docs a few times, but either I must have some odd
"Scribble-blind-spot" or something, or this is much more involved
than I imagine it really is.
I'm hoping a few illustrative source examples would help get me
started, and maybe a just a bare bones, simplified "how to" to
