The primary goal of the language constructs in this section is to enable high-level, safe code without having to pay a performance penalty.

([Pending](https://github.com/lampepfl/dotty/pull/4028)) An opaque alias defines a new type `A` in terms of an existing type `T`. Unlike the previous modeling using value classes, opaque types never box. Opaque types are described in detail in [SIP 35](https://docs.scala-lang.org/sips/opaque-types.html).

Erased parameters improve both run times (since no argument has to be constructed) and compile times (since potentially large arguments can be eliminated early).
