To go further, while this trick is great, there's been
discussions [last
years](https://forum.dlang.org/thread/[email protected]) about _Parent Enum Inference_. Instead of

bitset |= 1 << EnumType.enumerator;
```
people want to the language to allow writing
```
bitset |= 1 << .enumerator; // EnumType can be infered from
the OrAssign LHS
```
How can it be inferred? There's no expected type for the
right-hand side of the `<<` operator. Of course the link has
cases that could be inferred.
in this case `with` is of no help because it introduces a
scope, because it's not an expression, and finally because
it's only used once.
Yeah you're right with that remark... better example
```
bitset |= .enumerator
```
assuming the C style with the pre-shifted value defined for each
enumerator.
