  Comparison between Java and Common Lisp solutions to a phone-encoding problem described by Prechelt

FYI I changed Rust to use a Vec just to see if that really makes it much faster...

Using an enum to simulate dynamic typing: https://github.com/philipc/prechelt-phone-number-encoding/tree/rust-number. This should be similar to the performance improvements from something like https://github.com/rust-num/num-bigint/issues/36, which means suboptimal use doesn't hurt as much.
