Interesting programming language: F#

Has anyone coded in F# before? It looks fantastic, but since it was created by Microsoft I don’t expect a version I can use any time soon. but I like the way it describes and separates mutable and immutable data. I like the way it blends functional programming with object oriented stuff, and the way it is compatible with preexisting libraries written in other languages. I like the static type system and the type inference on top of it. It’s got a lot of cool things reminiscent of SML (or OCaml, presumably, if I knew it better) while at the same time keeping an imperative, object-oriented spirit about it.

I’m not wild about some of the syntax, particularly the way it’s hard to tell where the definition of a type ends. and that weird <- operator for storing mutable data. and the bizarre [|...|] delimiters of arrays. and the whole #light declaration and how that totally changes syntax (just pick one way or the other and stick with the decision). But so far my biggest complaint is the syntax, while everything else about F# seems pretty cool. Has anyone actually played around with F#? I'd be interested in hearing how it works in practice.

Tell me about your ideal programming language.

Suppose you could create the specification for your ideal programming language. It must be possible to implement (it can’t solve undecidable problems, etc), but other than that the sky’s the limit. What would you put in it (what kind of syntax, intrinsics, etc)? For what sort of applications would it be used? What other features would it have? Would the interpreter/compiler do anything unusual? Tell me anything you want about your ideal language and the tools that go with it. You’re welcome to answer some of these questions if you don’t have answers to all of them.

I’ve been asking variations of this question to all sorts of people, and it’s fascinating seeing where they agree and where they don’t.
