cache variable

Creates a @cache() method decorator that memoizes the decorated method's result in a cache adapter (RedisCache by default). On each call the cache is checked first; on a miss the method runs, and its result is stored under a key derived from the class name, method name, and arguments. The returned decorator is dual-mode: it works both as a standard (TC39) and as a legacy method decorator.

Signature:

cache: CacheDecorator
