After reading this mail I did a few tests with the 'alias word to see if such thing was feasible, but I went too fast and tried this :
>> alias 'first premier ; premier is french for first
** Script Error: premier has no value the error is logical since "help alias" reveals that alias expects a string as its second argument. So I retried (in the same console) :
>> alias 'first "premier"
** Script Error: Alias word is already in use: premier
>> premier [1 2 3]
** Script Error: premier has no value ** Near: premier [1 2 3] Isn't it a bug from 'alias ? It seems that premier was only partially registered as a word by alias which renders correct further aliasing of that same word impossible. But to answer back to Tim, it seems like it's possible to have an entirely french rebol by simply aliasing all rebol words with their french equivalent. Note that it must not be done carefully (ie can't be automated using an english/french dictionnary) since quite a number of them are the same in english and french (type?, change, date, difference, exp, unique?, zero, ...) and others do not have strict equivalent in french (struct for instance). I find it nice that 'alias allows Rebol to be completely translatable but it might become quite a problem if this becomes widely used : everyone will need a copy of the alias definitions along with a non-native rebol script to be able to execute it. Add to this that it will be very difficult to understand what the script does if you don't know the language :) But another rebol script might do instant language conversion easily so this is not really a problem I guess.

Well, IIRC it is documented in the core guide, that 'alias can only alias to words, that have never been used before. Where "used" means it should never have been seen by rebol as a word, because the rebol interpreter saves everything it has seen as a word to system/words.

Ain't rebol great? Maybe I actually could learn French using rebol.... well, after I get the Yupik down. I have heard it said (and can't recall the source...) the one of the languages spoken by indigenous peoples in the southwestern U.S. could express concepts of quantum mechanics better than english... (was it hopi? I don't recall). -tim- * Ingo Hohmann <[ingo--2b1--de]> [020921 13:46]:
