/**
 * `o` is a curried composition function that returns a unary function.
 * Like [`compose`](#compose), `o` performs right-to-left function composition.
 * Unlike [`compose`](#compose), the rightmost function passed to `o` will be
 * invoked with only one argument.
 *
 * @func
 * @memberOf R
 * @since v0.24.0
 * @category Function
 * @sig (b -> c) -> (a -> b) -> a -> c
 * @param {Function} f
 * @param {Function} g
 * @return {Function}
 * @see R.compose, R.pipe
 * @example
 *
 *      var classyGreeting = name => "The name's " + name.last + ", " + name.first + " " + lastName
 *      var yellGreeting = R.o(R.toUpper, classyGreeting);
 *      yellGreeting({first: 'James', last: 'Bond'}); //=> "THE NAME'S BOND, JAMES BOND"
 *
 *      R.o(R.multiply(10), R.add(10))(-4) //=> 60
 *
 * @symb R.o(f, g, x) = f(g(x))
