Ruby 2.0 backwards incompatible changes

From Peter Cooper's Walkthrough:

• lines, bytes, chars, codepoints returned an Enumerator in 1.9 -> use each_lines, each_bytes, each_chars, each_codepoints instead for an Enumerator
• # encoding: utf-8 is the default (which impacts regular expressions that expect it to be us-ascii, eg. vpim)
• respond_to? on a protected method returns false (was true)
• inspect doesn't use the redefined to_s
• Array#values_at returns nil for each number outside of the array
• CSV.dump & CSV.load are gone (object serialization)
