Hello Everybody,

I know I can parse multiple arguments in Clap into Vec<T> - for example clap/examples/escaped-positional-derive.rs at master · clap-rs/clap · GitHub

I also know I can use #[arg(last = true, value_parser = |inp: &str| ... with a function that will be applied on each T in Vec<T>.

But I can't figure out if I can somehow pass the whole collection/iterator to a function. For example if I want to get VecDeque<T> without converting it afterwards from Vec<T>. Is that possible?

Thank you.
