Sure,
map and filter are more usual, but reduce is not far behind.
you use map and filter to reduce a structure down to a value? Or
do you mean it's just something you use often?
I don't think map+filter can be used to "reduce" a range down to
a value. It would require a filter with mutable state, and I'm
pretty sure doing that means having an implementation defined
result.
