But isn't this exactly the point I was trying to make!? The whole point,
to me, in functional programming, is that we shouldn't have to worry about
the underlying implementation. What you've listed above are the restrictions
of a particular compiler implementation. All of which, if needed, can be
controlled by a flag if compilation performance is so important.
