Subject: Re: Iterate Array and (pretty)print

Except, I need to put the output into a string.  When I use the to_s 
method, I end up with square brackets and quotes:

irb(main):001:0>  @hosts = ["test1", "test2", "test3", "test4"]
=> ["test1", "test2", "test3", "test4"]
irb(main):002:0> puts @hosts
test1
test2
test3
test4
=> nil
irb(main):003:0> puts @hosts.to_s
["test1", "test2", "test3", "test4"]
=> nil
