No, because the declaration is guaranteed to follow in the same unit.
A unit forms a self-contained whole.

Unit loading is a difficult matter as it is. If you start spreading 
declaration and implementation over different units, I'm not sure that
the compiler can guarantee correctness.

But Florian should answer this, he is more knowledgeable about the
compiler internals.
