This archive holds a full interpreter for a lazy (in fact full call by need) dialect of Scheme for the MacIntosh. The interpreter is complete and efficient (as a matter of fact, fib 20 takes 5.4" on a 68030/25Mhz emulated Mac). The only limitation is that you absolutely need a 68020 (or more) and an 68881 (or more) if you want to use floating points (or use a software emulator).
The application is Help-Archive:Paresseux. It should be used with its start file !
Docs are included in Word4 and Ascii formats in Help-Archive:Docs in both English and French.
If you have much memory, you should change the memory for Help (Just ask the info on the application "Paresseux" and modify the silly 512Ko to something more interesting).
There are some templates for Resedit in Help-Archive:Divers to edit the "Paresseux" application, allowing to change default font, stack usage, procedures and special forms names…
