How to use Arg(name='xxx')？

[wu-clan]

When I use Arg(name='xxx') to define the parameter name, it always prompts me: ValueError: Arg 'name' cannot be set when using automatic inference.

I think name replaces the default uppercase arguments name

Maybe it's still a little different than I thought, I'm trying to achieve something like the metavar parameter in Typer by modifying name to the input type

Effect Comparison：

typer define the input type using typer.Option(metavar='xxx')

cappa contains uppercase arguments without input types

Created an issue for this: #46, tl;dr missing feature currently, should be straightforward to add

So Arg("foo") or Arg(value_name="foo") should work as of v0.10.0
