Discussion on: C# and .NET Core Appreciation Post. The most beautiful piece of code I have ever seen... this month!

I want to wholeheartedly thank you for this article. I considered LINQ syntax so useless, I forgot about it when trying to figure out how to bend C# to my needs. Thanks to you, I started to wonder what LINQ actually could be useful for, and it has a use!

It can be used to add monadic 'do' syntax sugar. I missed this for a long time, creating all sorts of workarounds. Inventing ways to use the language in manners the language was never meant to be used. (Not stopping now, lol)

Now, I finally found a use for LINQ syntax. I didn't implement it yet, but I am nearly certain it's possible. Implementing the specific SelectMany on my custom type, I should be able to write 'nested' bind calls (thus able to reference previous variables) as a flat sequence of operations.
(I just hope there is not some horrible trap, like there is in mutable async blocks (which makes them useless as generic monad syntax))

var r = from a in m()
        from b in m()
        let aa = a + b
        from c in m()
        select new { aa, b, c };

Imagine m() to be some monadic expression.

If this works, my code will be so much more readable and maintainable thanks to this. ^^ - And if it wasn't for you, I would have never thought about this. So, thank you. ^^
