# The above rails definition has some problems:
#
# 1. { 'foo' => /bar/ }.to_json # => "{foo: /bar/}"
# This isn't valid JSON, because the regular expression syntax is not
# defined in RFC 4627. (And unquoted strings are disallowed there, too.)
# Though it is valid Javascript.
#
# 2. { 'foo' => /bar/mix }.to_json # => "{foo: /bar/mix}"
# This isn't even valid Javascript.
