Hopefully, it would be easy to implement it "manually":

function PreInc(var value: T; Delta: Integer = 1): T;
function PostInc(var value: T; Delta: Integer = 1): T;
function PreDec(var value: T; Delta: Integer = 1): T;
function PostDec(var value: T; Delta: Integer = 1): T;

(with obvious implementation for any T supporting operator +/-).
One could even think of something like:

function generic<T> PreInc(var value: T; Delta: Integer = 1): T;
function generic<T> PostInc(var value: T; Delta: Integer = 1): T;
function generic<T> PreDec(var value: T; Delta: Integer = 1): T;
function generic<T> PostDec(var value: T; Delta: Integer = 1): T;

But... let's don't go there, generics are still not fully functional
in their present form.
