I'd be interested in helping with iOS apps (writing bindings etc)<br>
provided someone<br>
solves the initial hurdle: getting Racket to cross compile to iOS and get it<br>
running on an emulator (and later an actual phone/tablet).<br>
<br>
There might be some hints (wrt compiler switches) here:<br>
