With ArgParse.jl, how can I parse key word arguments like `--myoption 1` while ignoring all positional arguments, when the number of position argument is not fixed, i.e. “vararg”?

Simpler question: does ArgParse.jl (or a similar package) have support for variable numbers of cmd arguments?

I would be surprised if `ArgParse.jl` would not support this (but I never used it either …)

Anyways, did you have a look at their documentation?  
In particular this section here speaks about the `nargs` options: [Argument table · ArgParse.jl](https://carlobaldassi.github.io/ArgParse.jl/stable/arg_table/#Available-actions-and-nargs-values)
