Reg 0.5.0a0 Released
Reg version 0.5.0a0 has been released!
Reg is a library for pattern matching in ruby data structures. Reg provides Regexp-like match and match-and-replace for all data structures (particularly Arrays, Objects, and Hashes), not just Strings.
Reg is best thought of in analogy to regular expressions; Regexps are special data structures for matching Strings; Regs are special data structures for matching ANY type of ruby data (Strings included, using Regexps).

Changes in this version:
- new much faster backtracking engine (turns patterns into equivalent ruby to eval)

- beginnings of search-and-replace (but this doesn't work yet)
- ported to ruby 1.9+
- _ and __ are new preferred names for OB and OBS
- use something more like standard project structure
- taking a stab at backreference-like functionality
- support for utilities like inspect, hash, marshal
- trace operator for debugging
