The package is built with internal cache off. This feature should be
considered as highly experimental, and it has several critical issues.

 * There is no way to clear the cache at runtime.
 * Its maximum size is not fixed that may lead to memory leaks.
 * As well as it is thread-unsafe.

So the `key` parameter of the `loadFromData` method is silently ignored.
