I'll disagree with this. Viewed as a data structure, the implementation of compression algorithms is an excellent test of using a non-serialized language to implement a general structure with parallelibility,
if the compression algorithm has this and for picturing the resulting data streams in mental cognition space. the end result if properly done, should be extremely efficient. Nota bene: I did not say easy to do.
