     Returns a string created by converting each element of the array to
     a string, separated by _sep_.

        [ "a", "b", "c" ].join #=> "abc"
        [ "a", "b", "c" ].join("-") #=> "a-b-c"

$ irb
irb(main):001:0> [1,2,3,4].join
=> "1234"

% irb

x = [1,2,3,4]

=> [1, 2, 3, 4]

x.join('')

=> "1234"

I just tried this in irb:

irb(main):112:0> [1,2,3,4].to_s
=> "1234"

careful w that.

C:\family\ruby>ruby -e "puts RUBY_VERSION;puts [1,2,3,4].to_s"
1.8.6
1234

C:\ruby1.9\bin>ruby -e "puts RUBY_VERSION;puts [1,2,3,4].to_s"
1.9.0
[1, 2, 3, 4]
