RE: [sv-bc] enumeration types

 
I don't disagree with it being a scalar, I am just seeking confirmation that
this
is the only case (with a base type) where an enumeration type could be a
scalar
and we would have to check for bit selects or part selects and issue an
error.

Why is this NOT a scalar?
