/**
* `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. Also, unlike [`compose`](#compose), `o` is
* limited to accepting only 2 unary functions. The name o was chosen because
* of its similarity to the mathematical composition operator ∘.
*
* @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
*
* const classyGreeting = name => "The name's " + name.last + ", " + name.first + " " + name.last
* const 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))
