If you want `-o` to work by itself then you need an implicit argument. A default is so that you still get a value when `-o` is not provided at...

I didn't realise that the double underscore was reserved. I will make a new one and deprecate the current one in a future release.

Is having commas in your filenames common? The comma is only the default, you can redefine it yourself. I think removing this functionality is also not desirable because people now...

Yeah that's a good point. Doing this per argument might be more reasonable. This isn't just for positional arguments though. It's possible to have some non-positional arguments that can appear...

That's a difficult case to deal with. What if `--second` is a valid argument to `--first`. My parser doesn't treat values specially by recognising them as an option if they...

I also don't think this is completely unreasonable. See for example `grep`: ``` grep -e -E ``` it will quite happily look for lines containing `-E`, even though that looks...

I could make this configurable. Do you think it should be an error for anything starting with a hyphen to follow an option with a value?

That would need a bit of fiddling to do. Vector arguments are basically flattened out into a single vector, so I hadn't really thought of having a vector of vectors.

At the moment this can't be done. It's not really in the use case of the simple parser that cxxopts was designed to be. It could probably be implemented without...

Can you add a test case for this?
