You created an explicit implicit Array conversion by using "*" on the right side. The point Matthew and I were trying to make is that you cannot do the same with a range without the splat operator on the right side: irb(main):004:0> a, b, c = 0..2 => 0..2 irb(main):005:0> a => 0..2 irb(main):006:0> b => nil irb(main):007:0> c => nil Whereas with an Array you can: irb(main):012:0> a, b, c = [0, 1, 2] => [0, 1, 2] irb(main):013:0> a => 0 irb(main):014:0> b => 1 irb(main):015:0> c => 2 Cheers robert -- remember.guy do |as, often| as.you_can - without end http://blog.rubybestpractices.com/ -- [email protected] | https://groups.google.com/d/forum/ruby-talk-google?hl=en --- You received this message because you are subscribed to the Google Groups "ruby-talk-google" group.
