Hi,
I am getting into Ruby. I've only written one program so far, after a
week of letting
the main chapters of 'Programming Ruby' sink in.
It takes a dir of "Artist - title.mp3"s and move them to new folders
called "Artist"
Only about 7 lines of code. So it's a decent scripting language.
But the things Gopal mentioned are what are exciting about it,
as mix-in's and functional programming need to be coded
in Java as decorators and visitors design patterns.

PS.
I am having trouble understanding the syntax of 'inject'.
Does anyone understand how variables get set here?:
class Array
def inject(n)
each { |value| n = yield(n, value) }
n
end
def sum
inject(0) { |n, value| n + value }
end
def product
inject(1) { |n, value| n * value }
end
end
[ 1, 2, 3, 4, 5 ].sum >> 15
[ 1, 2, 3, 4, 5 ].product >> 120
