1) Install pict3d through DrRacket's built-in package manager - sudden, silent crash. Luckily I ran it from a terminal, which indicates an out of memory error.
2) Raise DrRacket's memory limit to "unlimited" and retry. Same result.
3) Google how to install packages from the command line. Wait for package to build. Build hangs during documentation. Eventually give up and ctrl-c. Hopefully it still works without docs? Racket packages aren't transactional, so every failed build leaves Racket thinking a package is installed, but it's actually broken.
4) Run DrRacket. Load pict3d and type oneliner. Incautiously press an F-key I assume will run the program. DrRacket crashes.
5) Run DrRacket. Load pict3d and type oneliner. Carefully run the program. Scene is incredibly slow but works! Then DrRacket hard crashes and locks my entire desktop so I have to go to a TTY to recover. My graphics are corrupted in a minor way. I haven't rebooted since then, and they're still corrupted.
I really, really like the look of Racket and want to use it in anger for a project, and I have a specific one in mind that would benefit from 3D, but this user experience is singularly bad. It's probably pict3d's fault, but there's no indication of this module being of "pre-alpha" stability. Or maybe it's an interaction with Racket-on-chez and C library interfacing. Let's hope it gets better.
