Yes. Apologies for getting interrupted (I have to actually do some work every so often). The spec doesn’t explicitly say it, but it makes it pretty clear IMO in section 7.6.10.2: An object initializer consists of a sequence of member initializers, enclosed by { and } tokens and separated by commas. (Note the word “sequence” … Read more
If the default values are not documented, the reason is likely that the optimal initial capacity is an implementation detail and subject to change between framework versions. That is, you shouldn’t write code that assumes a certain default value. The constructor overloads with a capacity are for cases in which you know better than the … Read more

You can vote for it there, as well as follow links into previous discussion around the feature. https://github.com/dotnet/csharplang/issues/307 If you’d like to see this feature, add … Read more

Here is what he says: This is an implementation limitation in the swift 1.1 compiler, documented in the release notes. The compiler is currently unable to destroy partially initialized classes in … Read more

From the documentation: The runtime sends initialize to each class in a program exactly one time just before the class, or any class that inherits from it, is sent its first message from within the program. (Thus the method may never be invoked if the class is … Read more
