Subject: Re: rubynuby - confused by method name "inject"

Following David's suggestion, I think I'll go ahead and use it, but 
always precede it with a comment so I can remember what it does when I 
come back to it later.  Something like:

# this "inject" method is "combining" the results from the block 
operation into a single answer
[1,2,3,4,5].inject(0){|sum,num|sum+num}


This topic makes me wonder, and perhaps one of the old-timers here can 
answer this.  If I understand it correctly, Matz basically "invented" 
ruby.  Matz is, as far as I know, Japanese.  Was Ruby first written with 
Japanese class and method names and later translated to English?  Or did 
it start out in English?

thanks,
jp
