Is your feature request related to a problem? Please describe.

I'd like the ability to define variadic arguments.

Describe the solution you'd like

static args = {
    value: Args.string({
        multiple: true,
    })
}

console.log(this.args.value[0], this.args.value[1])

Describe alternatives you've considered

I've set "strict = false" and pulled the args from "const {argv} = await this.parse(..)" as it's called out in the docs: https://oclif.io/docs/args/. This means to use variadic arguments you lose the syntactic sugar (and documentation) of the args definition. You also lose validation (e.g. number / string / etc).

In other words, I want variadic arguments with strict parsing.

Additional context

Previous issues:

• Variadic arguments in oclif oclif#160. This was closed with a recommendation to disable strict parsing. This means you lose the validation.
• "multiple" flag for args oclif#293. This was closed with a link to a pull request in the oclif/parser repository. feat: allow multiple for arg parser#63. That repository has been archived.

Other tools:

• Commander supports variadic arguments: https://github.com/tj/commander.js?tab=readme-ov-file#variadic-option
• Clipanion (what Yarn Modern uses) supports variadic arguments via transparent proxying: Option.Proxy -- I've had to hack something like this together in oclif to support unknown flags so they can be forwarded without disabling strict parsing of known flags though that's a separate issue.
• In Python, the stdlib for argument parsing supports variadic args via nargs: https://docs.python.org/3/library/argparse.html
