So in worst case, you use twice the amount of memory afterwards. Practically – a bit less, because Strings are often interned and will (usually) not … Read more

Arnold: If I were to be God at this point, and many people are probably glad I am not, I would say deprecate Cloneable and have a Copyable, because Cloneable has problems. Besides the fact that it’s misspelled, Cloneable … Read more
