Support overriding arguments

[richard-viney]

Hi, thanks for the great library!

Is it possible to specify arguments multiple times and have the last one take precedence?

E.g. my-app --name foo --name bar would be identical to my-app --name bar.

I know there is good support for array arguments, but using them to get the above functionality doesn't seem ideal.

Thoughts?

It's coming out in 1.3. See #39 and #38. Also #48. Seems like that was a really good suggestion, @lambdafu ! It's called take_lastand can even be set on the default argument for your app.

Sounds great, looking forward to the release :-)

I might change the default to take_last(true) before the release, since it seems that other common programs like git use it.

1.3 is released, and this is now possible.
