Sequence version 0.2.3 has been released!

- [GitHub - coatl/sequence: Sequence provides a unified api for access to sequential Ruby data types, like Strings, Arrays, Files, IOs, and Enumerations.](http://github.com/coatl/sequence)

Sequence provides a unified api for access to sequential data types,  
like  
Strings, Arrays, Files, IOs, and Enumerations. Each sequence  
encapsulates  
some data and a current position within it. Some operations apply to  
data  
at (or relative to) the position, others are independant of position.  
The  
api contains operations for moving the position, reading and writing  
data  
(with or without moving the position) forward or backward from the  
current  
position or anywhere, 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.
