Composing a list of functions
Composition of functions in F# is easily achieved by using the >> operator. You can also chain an arbitary amount of functions (represented as a list or sequence) together by folding the list/seq with >>. [More formally: the set of endomorphisms 'a -> 'a forms a monoid with the binary, associative operator ">>" (or "<<") and the neutral element "id".]

Seq.reduceBallanced function
The function has the same type as Seq.reduce. Instead of reducing elements from the left to the right, it splits the input into two halves, reduces each half separately and then aggregates the results using the given function. This means that the values are aggregated into a ballanced tree, which can save stack space.
