Ruby's regular expressions are almost identical to Perl's. The Master 
Regular Expressions book has a table comparing various language's 
support for regular expressions, including Ruby's. I don't think Ruby's 
regular expressions have changed since. The Ruby syntax is the same as 
other standard implementations, so modifiers, like /o at the end of a 
regex or (?: ...) for specifying modifiers within a regex are 
supported.  Jeffrey Friedl notes in his book the more advanced features 
that are not generally supported (by Ruby or other languages).
