From the callee's perspective, optional parameters are interpreted as the F# option type, so you can query them in the regular way that option types are queried, by using a `match` expression with `Some` and `None`. Optional parameters are permitted only on members, not on functions created by using `let` bindings.
 
 You can pass existing optional values to method by parameter name, such as `?arg=None` or `?arg=Some(3)` or `?arg=arg`. This can be useful when building a method that passes optional arguments to another method.
