What sort of silly comment is this?  There is no such thing as "bottom
up" or "top down" design -- there is good design and there is bad
design, and a good designer will think about his problem from an
overall standpoint (top down) and then based on this, create the
primitives that are needed (bottom up).  If you design programs by
indiscriminately creating primitives without any thought about what
they are to be used for, or if you think only in terms of high-level
algorithms and don't think about your low-level representations until
you are forced to, you are going to write a bad program.
