Description elpenguino+D 2023-08-22 00:24:14 UTC 
```
import std.bitmanip;

enum Bar : bool {
	a,
	b,
}

struct Foo {
	mixin(bitfields!(
		Bar, "bar", 1,
		ubyte, "", 7,
	));
}
```
This compiled before DMD 2.103.0. Now it produces two errors: 'Error: operation not allowed on `bool` `result <<= 7u`' and 'Error: operation not allowed on `bool` `result >>>= 7u`'.
