Without this assertion, the simple implementation (where there is no copy being made) will pass for both remove and removeWithoutCopy.

A better test would be to ensure that the original array is unmodified, because that's what we really care about. Can you just do this in #58 and we can close this issue?


Krinkle Jan 7, 2013

It is rather unlikely that an implementation will both make a copy and then modify both and return the copy. But ensuring the original is unmodified makes sense.

#58 and #59 are different pulls that include this due to merge conflicts, unrelated otherwise. Or do you want me to squash them into one pull request? (people usually prefer to keep them atomic and easy to review)

Krinkle commented Mar 6, 2013

See #59.
