 Here, the inferred type of `x` is `Set[Kind & Product & Serializable]` whereas one would have hoped it to be `Set[Kind]`. The reasoning for this particular type to be inferred is as follows:
 
- - The type of the conditional above is the [union type](new-types/union-types.md) `Val | Var`.
- - A union type is widened in type inference to the least supertype that is
-   not a union type. In the example, this type is `Kind & Product & Serializable` since all three traits are traits of both `Val` and `Var`.
-   So that type becomes the inferred element type of the set.

 Scala 3 allows one to mark a mixin trait as `transparent`, which means that it can be suppressed in type inference. Here's an example that follows the lines of the code above, but now with a new transparent trait `S` instead of `Product`:

 Typically, transparent traits are traits
 that influence the implementation of inheriting classes and traits that are not usually used as types by themselves. Two examples from the standard collection library are:
 
- - `IterableOps`, which provides method implementations for an `Iterable`
- - `StrictOptimizedSeqOps`, which optimises some of these implementations for

 Generally, any trait that is extended recursively is a good candidate to be
 declared transparent.

 The precise rules are as follows:

 The last clause ensures that a single transparent trait instance such as `Product` is not widened to `Any`. Transparent trait instances are only dropped when they appear in conjunction with some other type.
