 This is for state machine compilation of computation expressions that generate `IAsyncEnumerable<'T>` values. This is a headline C# 8.0 feature and a very large feature for C#.  It appears to mostly drop out as library code once general-purpose state machine support is available.
 
 ## Example: reimplementation of F# async
 
 I did a trial re-implementation of F# async (imperfectly and only a subset of the API) using resumable code. You can take a look at the subset that's implemented by looking in the signature file
