local arguments

[nrdxp]

Perhaps I missed it, but there doesn't seem to be a way for clap to support local arguments. Conceptually, something like:

#[derive(Parser, Debug)]
pub struct Args {
    inputs: Vec<String>,
    #[clap(local_to = "inputs", long)]
    r#as: Vec<String>,
}

So you can have cmd input_a --as foo input_b input_c --as bar, where the flag --as foo is associated with the input most closely preceeding it (i.e. input_a), input_b has no association, and --as bar is associated with input_c.

perhaps on the backend, clap could parse these input a single Vec<String, Option<String> for simple parsing from there.

The issue for this is #1704. A big problem with this is that there are a lot of ways of associating arguments like this. For example, your grouping looks different than any other grouping I've previously seen.
