Lingua::EN::Syllable::syllable() estimates the number of syllables in the
English word passed to it.
.
Note that it isn't entirely accurate... it fails (by one syllable) for about
10-15% of the words. The only way to get a 100% accurate count is to do a
dictionary lookup, so this is a small and fast alternative where more-or-less
accurate results will suffice, such as estimating the reading level of a
document.
