Co-Applicative programming style
The operator also pops up in George Wilson's 2018 talk, Contravariant Functors: the Other Side of the Coin, along with (>*) and (*<) operators to help things along. Shortly after its publication, Issue #57 for contravariant was raised, suggesting not only (>*<) but the other operators from George's talk.
