Marco, only if you happen to know from the top of your head, would it
be possible and without consequences to allow this kind of
construction? (i.e. a pointer reference to itself)
No. Because TMyRecord could be already defined in another unit.
Unit1.TMyRecord
Unit2.TMyRecord
is allowed as long as both units do not reference each other.
In case one of the two units reference each other there would probably be an
error message that TMyRecord is already declared and that there is a
conflict.
Therefore this error situation that you fabricated is already caught by the
compilers at least I know Delphi will.
Perhaps you are referring to a problem inside the compiler in relation with
the symbol table, in that case an easy fix would be to apply:
Unit1.TMyRecord, Unit2.TMyRecord so place unit name in front of symbol, but
this is probably already done since this is legal as long as they not
referencing each other.
