Subject: [ruby-talk:22405] list comprehensions alike Python ???

hello

a few days ago, I bought the "Python 2.1 Bible"
there (on page 51) is a cool feature described called
"list comprehension"

it works like this:

with python code like this:

l = [x * x for x in range(1, 11)]    

I get a list with squares of all numbers of 1-10

in ruby I could do this with the following code:

a = Array.new
(1..10).each { |elem|
	a[elem-1] = elem * elem
}

is there an even shorter way do to this in ruby??

regards
markus
