Hmm, maybe the root cause is the combination of selective import and unresolved
forward reference. Looks like "Merge pull request #1543" was a trigger for put
it in the table.

Technically, current "selective/renamed import" makes anonymous import
declaration and alias declaration. They have no internal relation, so forward
reference resolution is done separately. BUT, it should be together.

Yet I don't know well about the import mechanism. I need a bit more time to fix
it...
