I think you may have clipped some of the output. Here's what I get:

irb(main):005:0> 5.times {|i| puts i}
0
1
2
3
4
=3D> 5

It's puts'ing 0-4, and then returning 5. To see this more clearly, try thi=
s:

5.times {|i| puts "-- #{i}" }

The 5 you see is the return value of 5.times, which irb displays as it does=
=20
with the value returned by each expression you evaluate. If you try the abo=
ve=20
code from a script or from command line, you'll get the expected result:

ruby -e '5.times{|i| puts i}'

Ops, my IRB configuration is not helping me :)

Thanks for the explanation.
