RE: [sv-bc] RE: [sv-ec] That modport direction issue again

I think the LRM is equally unclear about what input directions means for
net ports of modules. I believe this is why no tool enforces port
directions on nets.

If someone declares a virtual interface with a modport, the only
operation allowed with an output is a procedural assignment. If you
stretch the longest static prefix rules to include virtual interfaces,
then you have to assume that a procedural assignment to a virtual
interface member is a procedural assignment to that member in *all*
instances of the interface. There is no such thing as a static reference
to a virtual interface.

I agree the LRM is unclear about what input modport directions
means for net ports.
