//#region src/compat/function/curryRight.ts
/**
* Creates a function that accepts arguments of `func` and either invokes `func` returning its result, if at least `arity` number of arguments have been provided, or returns a function that accepts the remaining `func` arguments, and so on.
* The arity of `func` may be specified if `func.length` is not sufficient.
*
* Unlike `curry`, this function curries the function from right to left.
*
* The `curryRight.placeholder` value, which defaults to a `symbol`, may be used as a placeholder for partially applied arguments.
*
* Note: This method doesn't set the `length` property of curried functions.
*
* @param {(...args: any[]) => any} func - The function to curry.
* @param {number=func.length} arity - The arity of func.
* @param {unknown} guard - Enables use as an iteratee for methods like `Array#map`.
* @returns {((...args: any[]) => any) & { placeholder: typeof curryRight.placeholder }} - Returns the new curried function.
*
* @example
* const abc = function(a, b, c) {
*   return Array.from(arguments);
* };
*
* let curried = curryRight(abc);
*
* curried(3)(2)(1);
* // => [1, 2, 3]
*
* curried(2, 3)(1);
* // => [1, 2, 3]
*
* curried(1, 2, 3);
* // => [1, 2, 3]
*
* // Curried with placeholders.
* curried(3)(curryRight.placeholder, 2)(1);
* // => [1, 2, 3]
*
* // Curried with arity.
* curried = curryRight(abc, 2);
*
* curried(2)(1);
* // => [1, 2]
