'<&>' calls '<$>' with flipped arguments. This was proposed by David Feuer (https://mail.haskell.org/pipermail/libraries/2016-August/027293.html) and solves #14029. The implementation is a copy of the '<&>' operator in Control.Lens.Lens. Add tests for following Data.Functor operators: '<$>', '<&>', '<$' and '$>'. '<&>' was added for solving #14029. '<$>', '<$' and '$>' were probably untested.
