I'm trying to fit a where clause to some guards I'm using. I have the
following
f a b
| c 1 = ...
| c 1 = ...
| otherwise = ...
where c = a+b
yet I'm getting a parsing error. Is this not the correct way to combine
where with guards?

There's nothing wrong with the use of your example, I'm guessing it's
something in your ... that's leading to the parse error. This compiles
just fine:
f a b
| c 1 = 1
| c 1 = 2
| otherwise = 3
where c = a+b

Well, perhaps you can help me figure out the problem with my exact program.
Just in case it matters, the program draws a Mandelbox via volumetric
ray casting. I can provide more information about the function, but I
wouldn't think it's necessary, since my problem is with parsing. The

Is there an easy way to install this module on Windows?
I just ran

I actually have some of these libraries installed (eg. expat) but not
most.
I'm using MinGW.
As I understand the use of where clauses in [1], A where clause is
only allowed at the top level of a set of equations or case
expression, would mean that the first where is scoping over the
whole traceRay function: the where m = shouldn't be there, since
there's already a where clause in scope.
Ugh, my formatting got eaten up by gmail. I just removed the where in
front of m =, and aligned tat statment with your ballFold
definition. I would also align the first where statement with the case
bars of traceRay.
