[F#] Implementing Coroutines (async/await) using continuations

Coroutines or async/await is not a new concept as it was named in 1958 by Melvin Conway. Coroutines had support in languages such as Simula(1962), Smalltalk(1972) and Modula-2(1978) but I think one can argue that coroutines came into mainstream with C# 5(2012) when Microsoft added async/await to C#.

The problem with subroutines

A thread can only execute a single subroutine at a time as a subroutine starts and then runs to completion. In a server environment subroutines can be problematic as in order to service connections concurrently we would usually would start a thread per connection, this was the idiom a few years ago. A thread depending on the operating system and settings needs about 1 MiB of user stack space meaning 1,024 threads needs 1 GiB of for just user stack space. In addition there's the cost of kernel stack space, book-keeping and scheduling of threads. This drives cost of VM/hardwa

PowerShell's casting can result in some weird results.

Check out User.cs down below. It's a pretty simple class with three constructors: the default (parameterless) one, and one each taking the user name, and id. PowerShell will cast using the constructors of a type, so in this case, you can cast either a string or a number --or a hashtable-- to User.

We can add this type to our PowerShell session using Add-Type:

Add-Type -path User.cs
