Is there operator for f# that works like ?? in csharp

[Xyncgas]

If there is a value myVal : Option<'T> that's None I would like to provide an alternative without writing match by
let x = myVal ?? AnotherValue

No, there is not. I tried doing something like that but C# has special handling of this operator (especially precedence).

Option.defaultValue/defaultWith is the way to go in F#.
