Not as easy as you would think:
     int i;
     switch(i) {
         case 0: .. case 9:
             break;
         case 10: ..case 10000000:
             break;
         default:
             break;
     }
-->  Error: had 9999990 cases which is more than 256 cases in 
case range

The FE always lowers CaseRangeStatements into a list of 
CaseStatements, so LDC currently has the same limitation.
