I don't think it is a good idea to allow tools to use different
sizes for different unsized constant values. Since the sizes
can affect the widths at which expressions are evaluated, this
would potentially introduce unpredictable and unexpected behavior.
For example, your suggestion would allow a tool to evaluate "1+1"
as 0 instead of 2, because it would be allowed to treat the two
constants as 1 bit, resulting in a 1 bit result size which overflows.
