/**
* Performs right-to-left function composition using transforming function. The rightmost function may have

*
* **Note:** The result of compose is not automatically curried.

* @memberOf R
* @category Function
* @sig ((* -> *), [(y -> z), (x -> y), ..., (o -> p), ((a, b, ..., n) -> o)]) -> ((a, b, ..., n) -> z)
* @param {...Function} ...functions The functions to compose

*
* composeWhileNotNil([R.inc, R.prop('age')])({age: 1}) //=> 2
