what about...

puts (1..10).to_a * "\n"

Ok now I doubt you could make this any shorter
1
puts (1..10).to_a

This also works, though it isn't shorter. It looks nice, though.

You could save that line into a separate file as a library, and then actually call it really easily!

I think we have a winner... the
puts *(1..10)
!
but actually
p *(1..10)
works too :)

AFAIK, you can lose () also ? Another 2 characters down...

Using range is really cool thing In ruby.
Also, .times is cool feature
Thanks,

Brian,
All ruby loops are cool and creative. Whether range or times or until. It is just great programming language.
Thanks

Using range is cool. I would also suggest using times. Like
10.times do |x|
puts x
end
Thanks

@Sakari, I don't this is "stupid," if you're trying to learn Ruby (like me).
Anyway, I think that do end is the same as {}, so could be written (shorter)...
[I'm sure my code will be totally weird here]...
Longer
1 2 3
10.times do |x| puts x end
Shorter
1 2 3
10.times { |x| puts x }

@Sakari, I don't think this is "stupid," if you're trying to learn Ruby (like me).
Anyway, I think that do end is the same as {}, so the translation is like this...
Longer With Do-Each
1 2 3
(1..10).each do |i| puts i end
Shorty with Braces
1 2 3
(1..10).each { |i| puts i }

@Daniel Rosenstark yes do / end and {} are both closure literals when in the correct context. {} us typically used for one-liners where as do / end in multi-liners (not always the case though obviously) this is a pretty funny exercise, the range splat is cool though. I am not sure exactly of the C implementation but splat does call #to_ary so you can do things like this
1 2 3 4 5 6 7 8 9 10 11
class Foo def to_ary return 1,2,3,4,5 end end def bar *args p args end bar *Foo.new # => [1, 2, 3, 4, 5]
How to make this shorter ?
