Thanks. I saw these, but couldn't quite figure out what I needed to do
for my program. I might add a note about helping the type-checker with
the array type overloading.

BTW, the STArray version of my code is honkin' fast (well, compared to
the immutable array versions). And memory usage is way down, too.
