What did you think of the code example given where the one-shot nature is
provided by a 'C' wrapper around the FFI function. I think this is the best
solution...

I might really want to call the initialisation twice. If you use global
variables, the library can only be initialised once... but what if I
really want to use the library twice? With the state in a type passed
between functions, you can have multiple different states active
at once.

Are your objections dogmatic, aesthetic, or rational?

I would have thought it would have been sensible to base floating
point maths on the IEEE spec, as thats what most hardware implements,
and there are libraries to emulate it for everything else. Does haskell use
IEEE primitives for things like sin/cos and sqrt? I am really surprised this

Well, its functional of course:
union :: Interval - Interval - Interval
union i j = Interval {
isin x = isin i x || isin j x
}
intersection :: Interval - Interval - Interval
intersection i j
I think someone else mentioned using functions earlier,
rather than a datatype why not define:
data Interval = Interval { isin :: Float - Bool }
Then each range becomes a function definition, for example:
myInterval = Interval {
isin r
| r == 0.6 = True
| r 0.7 r
.

The _result_ of a rather complex computation, so it has to
return a function that returns the handle.
for example:
handleOpener = complex function
bracket handleOpener close (\h - do
