Sure, this would be the best solution from my POV,
(only I would write it as
uses SomeBar = Bar in 'relative/path';
i.e. no unnecessary parenthesis and no starting './', since allowing
absolute path inside unit code is clearly insane anyway,
so they may be all assumed relative).
However, it was stated rather forcefully at the beginning of
the thread that FPC developers do not like this solution
(I am not sure why, and maybe I misunderstood).
Hence the need for your '-Fu' hack.

Of course, I was just saying that -Fu _must_ allow relative path
for aliasing to be useful for me.
