C# with LINQ での FirstOrDefault と ?? 演算子みたいなことを F# で書いてみる
// C# の ?? 演算子と同様の用途・目的で、|?? というユーザー定義の記号演算子をあらかじめ定義しておく。
// ただし null かどうかではなく、Option型の引数をとって Some(a) なら a を、
// None であれば第2引数に指定された既定値を返す仕組み。
let (|??) opt def =
match opt with
|Some(a) -> a
|None -> def
// LINQ の FirstOrDefault に近いのは、Seq.tryFind。
// Seq.tryFind は、集合の中から predicate で該当するものがあれば Some(a)、
