Suffers from all the usual problems. Try e.g.

123 1/2 Green Onion, Some City, CA

1/2 is treated as a number suffix (wrong, part of the number), Onion is treated as StreetPost, e.g. a classifier similar to Blvd. or Street.

Miss a comma, and the parser will be completely confused.

So, yay, now my address is going to be probabilistically wrong ;)
