<div>I guess that in some cases you don't want the default value to
be known, or is irrelevant. Most importantly, it can be a more
complex expression - e.g. creating an object and calling something
on it:</div>
<div><br class=""></div>
<div>private let mySecretNumber = 0x999</div>
<div>public func deinitialize(count: Int
= NSProcessInfo().processorCount + mySecretNumber)</div>
<div><br class=""></div>
<div>And that's a pretty example, it can get much nastier. Since
mySecretNumber is private, it definitely cannot be exposed.</div>
<div><br class=""></div>
