I guess I'm not the only one who's intuitive feel for "for" loops is
that they run to exhaustion (and, yes, it feels right to use for loops
to search a list for something and break when it's found, but even then
it feels like the program should be done with the iterable when the for
So it's interesting that the for statement is instinctively avoided in
this situation when it doesn't need to be (as it's currently defined).
