/**
 * Takes a combining predicate and a list of functions and returns a function which will map the
 * arguments it receives to the list of functions and returns the result of passing the values
 * returned from each function to the combining predicate. A combining predicate is a function that
 * combines a list of Boolean values into a single Boolean value, such as `R.any` or `R.all`. It
 * will test each value using `RA.isTruthy`, meaning the functions don't necessarily have to be
 * predicates.
 *
 * The function returned is curried to the number of functions supplied, and if called with more
 * arguments than functions, any remaining arguments are passed in to the combining predicate
 * untouched.
