Clap Version

3.0.0-beta.2

Describe your use case

The two main use cases I have for value names with multiple_values are

• 1 value name repeated repeated for each value
• Value name per value

Describe the solution you'd like

To catch mismatches in these, I'd like to have a debug assert so I know when I update one without the other

Alternatives, if applicable

1 value name repeated repeated for each value

That is a case of N:KN where number of values is a multiple of value names. (This is not supported in help message except when N = 1)

Good point about that generalization of the 1:N case. Not sure if it ever shows up but if we have usage support for it, I'm assuming someone requested it at some point.
