It can happen to the best of us.

｢ I swear that 20 years ago I promised myself that I would never touch .NET and here I am, promoting F# as a Golang developer. How did that even happen? ｣

2600+ downloads of v3 0.7.0 and there has been very little going on in the issues/discussions to make me think we aren't ready for 1.0.0.

If you haven't tried it yet, now's the time!

New to Functional Programming or interested in learning? Let's take it easy, by dissecting just one line of #fsharp code to explain
