learning ruby

this morning, i went to the "Learning Ruby" tutorial. it started off quite borring - it really was a beginner's tutorial it picked up pace after the break. Some interesting tidbits:
5.times { print "hello" }
This works because EVERYTHING is an object - even the integer 5.
["apple", "banana", "cat"].each_with_index {|fruit, i| printf "num %d is %s\n", i, fruit }
go through an array, and print each. Interestingly ruby puts the value before the key. Also, penny found a good explanation of symbols in ruby http://glu.ttono.us/articles/2005/08/19/understanding-ruby-symbols
