Strongly agreed. It could also increase a lot the memory usage (while on String we anyway already have the whole String in memory so it is less of a concern).

    File.open('/usr/share/dict/words').lines.each_with_object(Hash.new(0)) { |word, count| count[word[0].downcase] += 1 }

Bug #7440: IO#lines etc. should return Array

String#bytes, #chars, #codepints and #lines are changed to return Array in #6670.

For consistent behavior, following methods should return Array too:

* ARGF.lines, chars, bytes, codepoints
* IO#lines, chars, bytes, codepoints
* StringIO#lines, chars, bytes, codepoints
* Zlib::GzipReader#lines, bytes

Please let me know if there are more.
