program Circular;
{ Simple program that demonstrates newly-permitted circular
unit references via a USES clause in the implementation
section.
Note that it is NOT possible for the two units to
"USE" each other in their interface sections. It is possible
for AA's interface to use BB, and BB's implementation to use
AA, but this is tricky and depends on compilation order. We
won't document or recommend it.
