I think precondition is a better name because it clearly expresses that this is an expected precondition for calling the method. Precondition is similar to Microsoft code contract’s Contract.Requires.

Also, the traditional use of assert (also in other languages) is for guarding against your own programmer errors, which I think most people expect when they see assert. It may be useful for an assert that’s still active in optimised builds, true. I guess that could be called assert! or assertAlways.
