It is a common idiom to write a sequence of composed combinators in reverse order to the way they would be written with ($) or (.). That naturally expresses the idea of the combinators as operations being applied in the given order.
This comes up so often, and is commonly used so many times in a single expression, that Control.Arrow.>>> is far too wordy, and even a two- character operator is awkward.
Functional metapost called it (#). But for me (>>>) is ok. It is even more descriptive than (&).
