Subject: Re: help me condence my code?

putting it into phrase-test.rb and running it that way I get:

ph-test.rb:3: undefined method `delete_at' for nil:NilClass (NoMethodError)
        from ph-test.rb:10:in `each_with_index'
        from ph-test.rb:1:in `each'
        from ph-test.rb:1:in `each_with_index'
        from ph-test.rb:1

and relatedly, going through step by step I get:

023:0> end.delete_at(-1)
SyntaxError: compile error
(irb):23: syntax error, unexpected kEND
end.delete_at(-1)

I've never seen tacking things onto end before! is this possible?
