LINQ is so fucking useful and well designed feature of .NET ecosystem that it is unreal when you gotta use lang which doesnt have such a thing.

C# design team is/was unparalleled

If you like LINQ, you should really give F# a try.

F# is even better. I only wish performance wasn't hit or miss around sequences/iterator expressions. Hopefully one day it will reach parity with C# through compiler improvements and/or detaching FSharp.Core from conservatively targeting NS2.0 and modernizing it.

I never really got over the order-dependent and fairly slow compile times, but it's been like 10 years since I used it for anything even slightly complex. Is F# better in this regard now, or are there accessible patterns to help deal with that?

Order-dependency is a feature, not a bug, but it does take some getting used to. If you really want to avoid it, you can now declare all functions in a module to be mutually recursive, so you can put them in any order. Cyclic dependencies between files are still prohibited, for good reason. See https://fsharpforfunandprofit.com/posts/cyclic-dependencies/.

The F# compiler is slower than the C# compiler, but it's still more than fast enough for building large applications.
