Feature #1831
closedSuggestion: warn on repeated character in character class
Description
=begin
Suggestion: warn if the same character appears more than once in a character class (or more restrictedly: if the character ':' appears both at the start and end of a character class)
This is to give some indication of the problem if you do the following:
RUBY_DESCRIPTION
=> "ruby 1.9.2dev (2009-07-18 trunk 24186) [i686-linux]"
$WARN=true
=> true
"uber" =~ /[:lower:]/
=> 2
