FPC Generics.Default implementation is a little different than Delphi
implementation. There is no global function with additional instance/self
parameter, so I think the problem don't affect Generics.Defaults and i
don't need to change anything.

All is passed as "true" self parameter, there is no fake or trick :P.

All is achieved by "class function" method syntax, which always has "self"
