    According to the V2K BNF, the following module is illegal --

      module m_illegal ;
        parameter p = 1:2:3;
      endmodule

    and the following module is legal --

      module m_legal ;
        parameter p = (1:2:3);
      endmodule

    Was that the intent? Tools seem to be just as happy with
    m_illegal as with m_legal.

    If m_illegal is indeed illegal, how about adding an example?

    Likewise, according to the BNF, the following parameter assignments
    are illegal

       #(.p(1:2:3))
       #(1:2:3)

    and the following are legal

       #(.p((1:2:3))
       #((1:2:3))

    but the tools seem to be just as happy with the illegal versions.
