RE: [sv-bc] Bit/Part select of modport named argument

How can you distinguish a scalar from a 1-bit vector in this situation? I think the distinction disappears when used in an expression, and the self-determined type is the same.

"The self-determined type of the port expression becomes the type for the port." Shouldn't you be able to use the name of the port in any way that's consistent with its type? In this case, it has a scalar type, and it doesn't make sense to be indexing into a scalar type.
