What, you're telling me that "fast" software cannot be written in
Well anyway, speed is not my aim. My aim is to play with various
textbook algorithms an examine how well they work for various types of
data. As long as the code isn't *absurdly* slow that'll be just fine.
(I forget who it was, but a while back somebody pointed out the wisdom
of using Data.Map. It certainly makes the LZW implementation about 400%
faster! To say nothing of Huffman...)
BTW, how do the pros do Huffman coding? Presumably not by traversing
trees of pointer-linked nodes to process things 1 bit at a time...
