Delphi (now) provides Records with methods, but these lack inheritance. 
Why introduce such a crippled construct, when Objects can do the same 
and more (virtual methods...).

C bitfields are parts of some integral type variable, with each field 
spanning one or more bits. They allow to e.g. subdivide DWORD 
parameters, which consist of several parts (combined with OR).
