Very ingeniuos, I believe this is as close to a solution as I can get
for now.

But there are still a few probles I can see:
   - there is no way to "prefix" symbols within a unit, that I know of.
     Symbols may only be prefixed by the unit name directly. Is there a
     sort of a "namespace" in Pascal ?
   - if I make a wrapper unit around the third-party one, there is
     alredy little need for a prefix, since I can expose only the
     symbols I know of and that I use.
   - I find it even more tedious to do the same thing with the System
     unit or the standard Pascal units.

And then, if wrapper unit publicly uses the third-party unit, doesn't
that mean that all symbols in the thrid-party unit are now automatically
exposed and public in the wrapper unit ?

If so, is there a way to expose and make public the types, classes,
variables and functions from a private (implementation) unit ?

Thank you,
