Although I started the above project around the same time as Ramsey started his project in the original link (CLisp in Arabic), they were two entirely independent things. Ramsey's project is a 100% translation, whereas my project scales to other natural languages but is not a 100% translation.
Tim and I worked on trying to make programming in other languages easier as a means to help more kids learn programming, and learn FP the Lisp way, which we explain as more natural.
So, if you want to translate a lisp into another language you have to resort to macros.
* (symbol-function 'if)
#<CLOSURE (:SPECIAL IF) {1000C5084B}>
SBCL refuses to set that value to an alias: * (setf (symbol-function 'foo) (symbol-function 'if))
#<THREAD "main thread" RUNNING {10005205B3}>:
#<CLOSURE (:SPECIAL IF) {1000C5084B}> is not acceptable to (SETF SYMBOL-FUNCTION)
Trying this with regular functions works as intended: * (setf (symbol-function 'bar) (symbol-function 'mapcar))
#<FUNCTION MAPCAR>
* (bar #'1+ '(1 2 3))
(2 3 4)
Special forms are, well, special and a lot of the regular parts of lisp doesn't work with them.I expected specials to work in this case, but apparently not.
Variables may also have to be done with macros, because you want an assignment to a translated variable name to appear in the original variable. Some Lisp dialects perhaps allow a variable cell to have a binding to two or more symbols which could do the same thing.
