Weird "soundex" algorithm
I add a couple comments for posterity:
- All the solutions (except the original one) have the same problem: they don't care about upper-case vowels. All examples were in lower cases so nobody noticed it.
- The original implementation was wrong has it would consider consonant separated by a "non-first-vowel" as contigous ones and squash them if they are equal.
- The illustrious surname "Schwartz" with its consonant-to-vowel ratio of 7.0 render this algorithm pretty useless :)
