I can't agree more. Sometimes there is a valid design for something like 
that. The compilers already handle forward declarations in the same 
unit, so why can that not be applied for multiple units as well. And if 
the forward declaration is not fully resolved by the time the whole 
project or unit is compiled - raise a compiler error.

The current usage of forward declaration is exactly the same principle 
we are trying to use, but this time just across units.
