It adds the ability to more clearly express what you mean (“the containing class/struct, whatever it happens to be”), and it would reduce effort while reading code (in that you could see quickly that it was StaticSelf instead of having to look to see whether it was the same name as the enclosing type every time you read the code).</div></div></blockquote><div><br class=""></div><div>But if you don’t want subclasses to override it then why are you making it internal/public in the first place?</div><div><br class=""></div><div>I’m not sure the only-classes case of exposing a class/static publicly but also not wanting subclasses to override it justifies a new language construct. Accessing these things via Self (aka self.dynamicType) seems good enough to me.</div><div><br class=""></div><div><br class=""></div><div>Russ</div><br class=""></div><br class=""></body></html>
