Somehow relevant, has someone thought of turning Inc()/Dec() into functions
that return the modified value -like the Interlocked ones? I think this
would cover some of the cases discussed in a more "pascalish"
notation.Also, Include()/Exclude() could similarly be turned into
functions.

SqLite source can be downloaded and compiled with a C compiler (e.g.

I suggest that you implement this using interfaces. You place the
interface declaration in a common file, use the interfaces from the
main exe but implement them in separate dlls. This gives you all the
flexibility you want, e.g. group your methods into bundles and place
them on different interface

Hello all,
Does unit initialization in libraries (.dll files) work in arm/WinCE?
Somehow it seems that even code placed in the library initialization
begin end block isn't executed either. I found some bug reports (e.g.
0019404) suggesting that this didn't work for arm/Linux but it has
been added

Not for open arrays, but you can write an overloaded version without
the open array argument that calls the version with the open array

Sorry, I forgot to mention that advanced record syntax works in Delphi

You can use advanced record syntax and do something like this:
type
TRec = record
Numero: Integer;
Nome: String;
class function Create(ANumero: Integer; const ANome: string):
TRec; static; inline;
end;
