ruby -v: ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin12.4.0]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


=begin
On ruby 1.9.3-p448, a regular expression (({/[#$]/})) (character class which contains two characters, (({#})) and (({$}))) causes

    syntax error, unexpected $undefined.

Ruby 2.0 accepts this and (({Regexp.new('[#$]')})) is OK on both versions.
