Status:
Closed
Priority:
Normal

Description

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)

RUBY_DESCRIPTION
=> "ruby 1.9.2dev (2009-07-18 trunk 24186) [i686-linux]"
$WARN=true
=> true
"uber" =~ /[:lower:]/
=> 2
=end
