256 is reported to be the maximum number of cases allowed in a case range:
void main() {
switch (0) {
case 0:..case 257:
break;
default:
}
}
onlineapp.d(7): Error: had 257 cases which is more than 256 cases in case range
The error message is wrong about both the maximum allowed number (which is actually 257) and the actual number of cases (258 in the example). Something is off by one.
