/**
* The `Apply` class provides the `ap` which is used to apply a function to an argument under a type constructor.
*
* `Apply` can be used to lift functions of two or more arguments to work on values wrapped with the type constructor
* `f`.
*
* Instances must satisfy the following law in addition to the `Functor` laws:
*
* 1. Associative composition: `F.ap(F.ap(F.map(fbc, bc => ab => a => bc(ab(a))), fab), fa) <-> F.ap(fbc, F.ap(fab, fa))`
*
* Formally, `Apply` represents a strong lax semi-monoidal endofunctor.
*
* @example
* import * as O from 'fp-ts/Option'
* import { pipe } from 'fp-ts/function'
*
* const f = (a: string) => (b: number) => (c: boolean) => a + String(b) + String(c)
* const fa: O.Option<string> = O.some('s')
* const fb: O.Option<number> = O.some(1)
* const fc: O.Option<boolean> = O.some(true)
*
* assert.deepStrictEqual(
* pipe(
* // lift a function
* O.some(f),
* // apply the first argument
* O.ap(fa),
* // apply the second argument
* O.ap(fb),
* // apply the third argument
* O.ap(fc)
* ),
* O.some('s1true')
* )
*
