[fpc-devel] Problem with generic parameter

Independent of what Delphi may support or not (and I agree that at a minimum in $mode Delphi fpc should not require that IFDEF)… 


in a modern compiler I would expect the generic type parameter to be optional in this specific scenario and the compiler infer it from the type of the parameters.

Hi Sven,

Based on bug#20503 you are in charge of support for "generics"?
Thanks a lot for your work!

What about this incompatibility - is it a known issue?

        {$ifdef FPC}
        if Arrays<TTreeNode>.BinarySearch(changes.m_children,node,j,getComparatorByName) then
        if Arrays.BinarySearch<TTreeNode>(changes.m_children,node,j,getComparatorByName) then

Nope, that's not the same problem. Also the code example of the thread starter did not contain a generic method.
