I guess 32000 is small enough that a test won't be that expensive, but a python
script seems like overkill. Maybe use a bit of C preprocessor trickery like
the following:
```
#define CASES1(n) case n: case n+1: case n+2 case n+3:
#define CASES2(n) CASES1(n) CASES1(n+4) CASES1(n+8) CASES1(n+12)
#define CASES3(n) CASES2(n) CASES2(n+16) CASES2(n+32) CASES2(n+48)
void foo() {
switch (1337) {
CASES3(0)
break;
}
}
```
