            Bug ID: 25392
           Summary: Non-literals in integer widths
           Product: poke
           Version: unspecified
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: default
          Assignee: unassigned at sourceware dot org
          Reporter: john at cellform dot com
                CC: poke-devel at nongnu dot org
  Target Milestone: ---

Some formats (notably dvi) have records containing an integral field, where the
width of that field is determined by the record identifier.

It would be most convenient to be able represent this for example as:

deftype seti = struct
  int<8>                  opcode: opcode >= 128 && opcode < 131;
  int<(opcode - 128) * 8> character;

Other ways to represent this are possible, but they all require either a lot
more struct definitions or a lot of unions and conditionals.
