Delphi to C++ types mapping
- We can create table headers:
C++ |
Delphi |
---|
and avoid copying (C++) and (Delphi) for every row...
- We can segregate the C++ types by origin
- standard
- RTL (this is the #1 relation with Delphi here)
I think this can improve visibility.

Here's updated versions for WIN64. Please add a note that "System::*" types are accessible via the <System.hpp> header.
