Subject: [ANN] sequence 0.2.1 Released

sequence version 0.2.1 has been released!

* <http://sequence.rubyforge.org/>
* <http://rubyforge.org/projects/sequence>

A unified wrapper api for accessing data in Strings, Arrays, Files, IOs,
and Enumerations. Each sequence encapsulates some data and a current position
within it. There are methods for moving the position, reading and writing data
(with or without moving the position) forward or backward from the current
position (or anywhere at all), scanning for patterns (like StringScanner, but
it works in Files too, among others), and saving a position that will remain
valid even after data is deleted or inserted elsewhere within the sequence.

There are also some utility classes for making sequences reversed or
circular, turning one-way sequences into two-way, buffering, and making
sequences that are subsets or aggregations of existing sequences.


Changes:

### 0.2.1 / 2009-01-07
* 1 Minor Enhancement:
  * WeakRefSet now conforms to Set's api and tests more closely.

* 1 Bugfix:
  * fixed errors in MatchData when matching against a Regexp with an
    optional capture that didn't capture anything .
