Can FPC have default class properties in Delphi mode or even ObjFpc mode?
i probably won't really do it, for my major concern is still Delphi, and
that makes a special note that "defaul" and "class" are mutually exclusive.
Pity... i wished to do a light-weight factory (which Delphi class
references are to an extent). I would have to resort to global procedure,
but that is less elegant.
And calling TClassName.a(DataPayload) is awful. TClassName[DataPayload]
would be neat...
