Assuming I have a function like
foo = 8 + f1
where f1 = 8 + 9
f2 = 8 + 10
f1 clearly has to be evaluated, but f2 doesn't have to be. Will it be though? I can see how evaluating every where expression would be a performance issue.
Is the "where" keyword lazy?

Yes, it's lazy, so that
f2will not be evaluated, for example:will be calculated instantly, and would take forever if it was strict.
