I apologize for my previous post.  It occurred to me that Robert might
be right, and of course he is.  There isn't a form for self-closing
files unless I add it (per Pickaxe1).  Sorry.

FWIW, the correct form would be

File.open(path) { |file|
    file.each do |line|
        @text.push line.chomp
    end
end

I.e., I need another level of nesting.
