[fpc-devel] IComparer vs CompareFunc

I am trying to have some code that uses generics to compile under Delphi
and under FPC (uses fgl)

In Delphi I pass IComparer<T> and in FPC TCompareFunc<T>

IComparer<T> is an object and I can create it with some state that compare
method can use :)

In FPC I should pass function:

TCompareFunc = function(const Item1, Item2: T): Integer;

And I am not sure where I can add my state information that compare will
use - it is not and object function :(

Any help will be appreciated!
