reg 0.5.0a0

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).
