Interesting. Seems to suggest that maybe the cases I discounted
as being infrequent aren't so infrequent? Another possibility
is that the new coding adds more cycles to foreach() loops than
I'd hoped for.
Anyway, it's just a POC; the main point at this stage is to be
able to make such comparisons at all. If it turns out that we
*can't* make this into a win, then all that bellyaching about
how inefficient Lists are was misinformed ...
