</div>Thats mainly because the solution space was new and lots of unexplored<br>
terrain.<br>

</div>There really isn't a combinatorial explosion, but rather a small number<br>
of families of packages.<br>

</div>Java has been around 20 years. The iteratee/enumerator/iterio/conduit/pipes<br>
idea has really only been around for a couple of years and I would be<br>
surprised it one of them (or a new one combining the best features of<br>
the others) doesn't come out the clear winner in the next year or two.<br>
