Spellcheck package

I've been working on wrapping spellchecking functions in objects. The obvious advantage is not having to remember calls to *_free functions. I'm also planning to add functions for getting suggestions for whole strings (space-delimited words). It would return an associative array of suggestions with the misspelled words as keys and arrays of suggestions as values. Additionally, I think a function for 'highlighting' misspelled words by inserting stings before and after each misspelled word (i.e. '<b>' before and '</b>' after). Suggestions for other commonly useful functions are welcome. I'm currently basing the design on libenchant's interface. For convenience, it'll have a pspell (actually aspell) backend as a default, which can be switched for enchant, if it's available. Does this seem like a good addition to PEAR? Nikolas 'Atrus' Coukouma
