This is not yet supported. A proof of concept implementation exists 
locally on my computer however. It will then look like this:

=== code begin ===

type
   generic TArray<T> = array of T;

generic procedure ProcessArray<T>(arr: TArray<T>);
begin
end;

begin
   // usage:
   specialize ProcessArray<LongInt>(someintarray);
end.

=== code end ===
