Description
=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.

=begin
This is consistent with (({"[#$]"})) in 1.9.3 so I will reject this issue.
In // and "" (({#$X})) interpolates global variable (({$X})). As (({$[})) is not a valid global variable you get an exception.

To people curious about why this does not cause error in 2.0, see #8651.

Yes, I meant $], it was a typo.
