What's the question for this answer? ;-)

IMO we're discussing the third case, when multiple declarations might
apply. Then the parser has to search the units in their order within the
uses clause, which is unrelated to the order of input files.

Why not try to resolve that reference later, e.g. after construction of
the content table?

So what? IMO you didn't understand the problem :-(

Well, maybe you don't see the wood for trees any more? ;-)

Perhaps it helps to look closer at the questions, before you give
answers to questions never asked?
