Even if the '|' is added before 'iz', this won't work on it's own. There has to be something after, i.e. '$' or '/'. If you run this regex on "travel", you would only match "tr" because of the way it is ordered.

Does not support by, biz, bg and so on.
The very problem is in that slice:
b(?:[abdefghijmnorstvwyz]iz)
it looks like it should be
b(?:[abdefghijmnorstvwyz]|iz)
