+/**
+ * Creates a new function that, when invoked, caches the result of calling `fn`
+ * for a given argument set and returns the result. Subsequent calls to the
+ * memoized `fn` with the same argument set will not result in an additional
+ * call to `fn`; instead, the cached result for that set of arguments will be
+ * returned.
+ *
+ * Care must be taken when implementing key generation to avoid key collision,
+ * or if tracking references, memory leaks and mutating arguments.
+ *

+ * @memberOf R

+ * @category Function
+ * @sig (*... -> String) -> (*... -> a) -> (*... -> a)
+ * @param {Function} fn The function to generate the cache key.
+ * @param {Function} fn The function to memoize.
+ * @return {Function} Memoized version of `fn`.
+ * @example
+ *
+ *      let count = 0;
+ *      const factorial = R.memoizeWith(Number, n => {
+ *        count += 1;
+ *        return R.product(R.range(1, n + 1));
+ *      });
+ *      factorial(5); //=> 120
+ *      factorial(5); //=> 120
+ *      factorial(5); //=> 120
+ *      count; //=> 1
