<p dir="ltr">I've been getting a fair bit of mileage out of the 2htdp/image and allied libraries to do exploratory programming with an emphasis on graphics.</p>
<p dir="ltr">The abstractions are very nice, so I keep using them. It seems that what's good for novices is also good for fun programming, and good for me.</p>
<p dir="ltr">I do occasionally bump into tradeoffs made for instructional purposes: e.g. how above and beside fail when they only have one argument, and now would appreciate a more performant version of big-bang.</p>
<p dir="ltr">What's the step up from 2htdp/image? Is there a more general argument to refractor these libraries into "serious" and learning layers?</p>
<p dir="ltr">It seems to me that part of the promise of the Lisp family is to come up with better and better and cleaner and clearer abstractions and libraries.</p>
<p dir="ltr">Hopefully the community can lend a hand to the core Racket developers on this .<br>
