> What about CCL makes you describe it as a “technological marvel”? The fact that it started out its life as 1) a full CL implementation 2) with an IDE that is still usable today (you can run the original CCL on an emulator and it is till competitive) which 3) included an interface builder that was super easy to used, in fact easier than anything that exists today AFAICT, and 4) ran on a machine with 1MB of RAM and an 800k floppy disk. The other thing that CCL had/has was a blazing fast compiler. It was/is fast enough that it was/is practical for me in many cases to recompile my code from scratch every time I run it.
