Coercion of scalars to vectors

An integer expression is coerced to a vector expression whenever:

• it is combined with a vector by a binary operator or conditional, or
• it is assigned to a vector of signals

The length of the vector representation of an integer is 32 bits. The shorter of the two argument vectors is then padded with zeros before applying the operation.

        [0,1,1] + 17

yields a 32 bit vector representation of the number 20.
