Good to see mention of the lisp landscape on Macs overall. MacScheme+Toolbox was a really nice product for building real apps. It’s often overlooked in lisp and Mac history.
Also neat the clozure-cl is entirely open source now. You can download it via tarball or even Homebrew if you’re on OSX. It’s an extra step to build the GUI but pretty neat to get what used to cost metric tons of money for free.
And on modern hardware, the GUI builds in under a minute!
Yeah, I thought the same thing when I tried it out. Those of us who’ve been around a while remember waiting for seeming YEARS while Franz or similar CL implementations dumped images to disk :)
