## Description:
Putting this patch into the pipeline finally since I believe it to be finished, although I haven't got much feedback on the implementation. Tests with the prefix tgenimspez*.pp are included.
Full source is at https://github.com/genericptr/freepascal/tree/generic_implicit.
## Additional information:
Please note that the no-op lines in htypechk.pas are strange line endings (0x0d) which I believe to be errors in the original sources since I have not encountered this is any other file.
