Both of which have been in F# for years, and C# re-implemented them later, poorly. F#'s dynamic is extensible (and around since 2007? 2008? earlier?)). If you wanted to implement a "dynamo" object, go ahead. If you want loosely typed CSV-reader access, go ahead. (You get the ? and ?<- operators to define as you'd like.) C#'s async comes from F#'s async (available since Oct 2007), which in F# is just a library. That's because F# supports workflows aka computation expressions aka warm fuzzy things. What F# does as a library feature, C# requires baking into the compiler. So for 5 years now, MS has added these two features. They've still yet to deliver a REPL, or finish implementing type inference, or any such stuff. It looks like Anders Hejlsberg, the main C# designer, seems more interested in adding some basic features to JavaScript, lately. C# seems fairly abandoned, language-wise, to me. They seem to be content to have put Java in its place, and leave it at that. P.S. C#'s a great language, and I'm not trying to insult the people that have done great work on it. As a popular language, it's one of the nicest ones out there IMO. |

I take your point about pace, though. I wonder how it compares over the same timeframe vs other languages? In the 5 years for C# to cover that distance, what have other languages achieved? The biggies are particularly interesting (JavaScript, Python, Ruby, Java, C++, etc) because users probably demand more in terms of support and compatibility. (For others contributing, I'm thinking language-specific, so not libraries, frameworks, or runtimes, just pure syntax.)
It's also worth throwing uptake into the mix here; it's not much use if there's a version of the language defined in a spec but everyone's using the compiler from 1999 (JavaScript, I'm looking at you) I'm not a pythonista but I understand Python 3 has struggled with uptake, too. Not too sure of the details; happy to be corrected.
