'Sufficiently long' is doing a lot of work though. 1$a}F is a five symbol password and so is ASufficientlyLongPassPhrase. Unless an attacker has some specific knowledge about how the passwords were generated, the latter is significantly more secure since the dictionary size for the symbols (English words, though none especially uncommon so top 5k or so should suffice) is significantly larger than that of the former (standard keyboard characters). But it's not nearly as secure as a password in the style of the former with the same number of characters as that passphrase.
