    Actually "parameter foo = 1'b1;" is a special case for backward
    compatibility with Verilog-1995. It is treated as an untyped parameter
    that takes its type/size from the value assigned. However,
    "parameter [1:0] foo = 1'b1;" follows the same pattern as the rest.

    This might be going too far, but a logical extension would also allow

      typedef [7:0] my_byte;
      
    to be equivalent to

      typedef logic [7:0] my_byte;

    Would this last piece actually make this consistent across all uses of
    data_type? Or are there more worms in this can?
