yeh i know :) ply was replaced by sly for good reasons. ply was - is
- FAST. it did not - does not - use classes because classes use up a
lot more memory and are slower. however with pretty much everyone now
possessing portable supercomputers, that's no longer so relevant.
the only reason i'm using it is because it's something i've worked
with about... five to eight times now. i forget :)
