 ### Introduction
 
 We propose to introduce a new type of structured concurrency task group:  `Discarding[Throwing]TaskGroup`. This type of group is similar to `TaskGroup` however it discards results of its child tasks immediately. It is specialized for potentially never-ending task groups, such as top-level loops of http or other kinds of rpc servers.

 ## Motivation
 
 Task groups are the building block of structured concurrency, allowing for the Swift runtime to relate groups of tasks together. This enables powerful features such as automatic cancellation propagation, correctly propagating errors, and ensuring well-defined lifetimes, as well as providing diagnostic information to programming tools.
