Description

Hey there! Now thatF# 5.0 was announced, I'd just like to get conversation started about supporting (or not) all the new features listed. Specifically looking forward to support for applicatives.

• It's a preview announcement, if I'm not wrong.
• Nonetheless, the 5.0 preview features should already be available (but untested) in the latest Fable releases (since 2.6.0). You'll have to enable the preview in your project file, of course:<LangVersion>preview</LangVersion>

Closing as duplicate of #2049, please feel free to reopen if you have to (or open specific issues if you encounter any).

Thanks! FYI I'm extensively testing the and! applicative stuff over here in FsToolkit.ErrorHandling.

any idea how I can pass the preview compiler flag to the fable webpack loader?

@realvictorprm As mentioned above, you should be able to just add it to your .fsproj file (as you would when you compile with dotnet).
