(2) Vector Type
The vector type is a fixed size sequence of scalar values. A vector
can be indexed resulting in a scalar value. Operations between a
vector and scalar will result in a vector with a size equal to that of
the original vector, whereas operations between vectors will result in
a vector of size equal to that of the smaller of the two.
The vector type is a fixed size sequence of contiguous scalar values.

between a vector and scalar will result in a vector with a size equal
