In C++ specifies constructors and conversion operators that don't allow implicit conversions or copy-initialization. In C# declares a user-defined type conversion operator that must be invoked with a cast. For MS SQL Server for-xml-EXPLICIT mode use the [for-xml-explicit] tag

I have two classes, one is privately derived from the other (because I don't want to expose the interface of the base). However later I want to create a reference to the base.
I can do it with a normal member function base() but not with a cast…

What is the effect of 'explicit' keyword on the Return Value Optimization (RVO)?
Following code works perfectly fine (showing RVO):
