The code below results in:

changing main to only import i results in:

Disregard that, here is the real bug. I removed the circular struct definition.

The code below results in:
i.d(7): Error: b.B at b.d(5) conflicts with c.B at c.d(3)

But if the selective imports are changed to non-selective public imports(
bug[314]
) the error is gone.
