Comparing C#, C++, and Delphi (Win32) Generics

C#, C++, and Delphi all have a generic type and method language feature. Although all three languages are statically typed, they implement generics in very different ways.

Static Analysis and Generated Code

In recent months, I’ve been thinking about the problem of static analysis in generated code. Static analysis means using tools like FxCop and NDepend (for .NET apps) lint (for C) and CodeHealer (for Delphi) to find potential problems in your source code. Generated code is code written not by a human being, but by [...]

Why Has the Size of TObject Doubled In Delphi 2009?

Because it has a new feature.
Mason Wheeler noticed that TObject.InstanceSize returns 8 (bytes). It turns out that this is new in Delphi 2009; in previous releases, TObject.InstanceSize returned 4. But when you look at the definition of TObject in System.pas, you don’t see any fields declared at all.
Four out of the eight bytes are consumed [...]
