* Support for named groups, look-ahead, look-behind, and other
  cool features!
* Support for other regexp syntaxes (Perl, Python, Java, etc.)

== Lacking features compare with perl 5.8.0

* \N{name}
* \l,\u,\L,\U, \X, \C
* (?{code})
* (??{code})
* (?(condition)yes-pat|no-pat)
* \Q...\E

  This is effective on ONIG_SYNTAX_PERL and ONIG_SYNTAX_JAVA.
