RE: [sv-bc] assignment pattern to scalar

I think that 6.9 et al clearly imply that scalars are not arrays.

"A data object declared as reg, logic, or bit (or as a matching user-defined type or implicitly as logic) without a range specification shall be considered 1 bit wide and is known as a scalar. A multibit data object of one of these types shall be declared by specifying a range, and is known as a vector. Vectors are packed arrays of scalars (see 7.4)."

At first glance, a seems to have neither "structure fields" nor "array elements".
But, depending on which array theory you accept, a scalar can sometimes be considered a zero dimensional array.
A "scalar array" has one element, whose index position is the empty vector of subscripts along each axis of the array.
If we accept this reading, then the description of array assignment patterns might be understood to assign the value 1
to a.
