Juste pour tester la méthode collect, suite à un article sur Ruby's Cube...

Le code :
(testé sous Windows XP ; Ruby 1.8.6)

# Benchmark for using collect 
#or naive method on enumerable.

users = ["toto", "titi", "tartempion"]

# Naive method
def meth1(users)
    names = ""

    for user in users
        names << "#{user} "
    end
    return names.chomp
end

# Collect is flashy !
def meth2(users)
    names = users.collect { |user| user}
    return names.join(' ')
end

# Benchmark
require 'benchmark'

Benchmark.bm(15) do |timer|
    timer.report('Barbarian method') {
        for i in (0...1000)
            meth1 users
        end

    }
    timer.report("Ruby's finest...") {
        for i in (0...1000)
            meth2 users
        end
    }
end
