20 years of extending C++: What can we learn?
summary
Twenty years of C++ extensions power a UI-first C++ Builder: concrete features are properties (using the __property keyword that maps reads/writes to fields or methods), runtime reflection that embeds type metadata into the binary but only for a TObject-rooted subset (RTTI for TObject subset), meta-classes that enable virtual construction from names and packages, and an object-oriented method pointer called a closure used for streamed event bindings; it runs in an Embarcadero clang branch and it works in production UI tooling.
