Bam looks really interesting, definitely a lot simpler than Sparkey, and the basic principle is the same. I have been hesitant to use perfect hashing for Sparkey since I wasn't sure how well it holds up for really large data sets (close to a billion keys). Impressive to write it in less than 300 lines of clean code!
