You can use a 0-size static array:
```D
struct mystruct {
	uint32_t mask_limit;   // Limit enum value that can be tested 
with mask.
	uint32_t value_count;  // Number of values after the bitfield.
	uint32_t[0] data;      // Bitmask + enumerated values follow.
}
```

Then you have to index with `mystructVar.data.ptr[i]` to avoid 
bounds checking.
