[REBOL] Re: Re : Rebol language aliasing ==> was {Re: FORUM REBOL}

From: tim:johnsons-web at: 21-Sep-2002 15:03

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]:
