FPS just implements some algorithms in imperative code and gives
functional interface to them. if you need one of implemented algorithms
- you can avoid programming imperative code himself. but that is true
for any other library. the only difference is that FPS will be much
more used than average lib. btw, is it possible to rewrite this
algorithm in more high-level way using FPS, of course with more or
less good speed?

and imperative for me don't mean "in IO/ST monad". imperative mean that
your program is sequence of steps required to compute result
instead of function that translates original object to resulting one
