There may be (and indeed, experience suggests, there will be) situations
where the potential call graph indicates a circularity (i.e. that there is
no order of elaboration which the compiler can determine will ensure that
an unelaborated subprogram is never called), but where there is, in fact,
an elaboration order in which normal execution of the program will not
cause an unelaborated subprogram to be called.>>

Well of coruse this is true, and is why a purely static solution cannot
be 100% accurate. But It is *very* rare, I would say non-existent almost,
for anything other than specially constructed tests to run into this,
and the limitation in expressive power from forbidding such cycles is
negligible.
