Sorry Alex, but I'm not convinced there's a strong need for this new `:allowed` option. What are the advantages over just using a [validation block](https://github.com/mdub/clamp#validation)?

Mmm, I get that a validation block doesn't magically extend the help text, but it's not that hard, e.g. ```ruby SIZES = %w(S M L XL) option "--size", "SIZE", "T-shirt...

Yeah, I think option groups would be a great addition. I imagine the DSL might look something like: ``` option_group "Authentication" do option "--access-key", "KEY", "AWS access key" option "--secret-key",...

Might get some tips about how to implement this from Go-lang's cli package: - https://github.com/urfave/cli#bash-completion - https://github.com/urfave/cli/tree/master/autocomplete

I'm having the same issue, but this work-around seems to be working for me: ``` if (typeof Cytoscape('core', 'expandCollapse') == 'undefined') { Cytoscape.use(CytoscapeUndoRedo); Cytoscape.use(CytoscapeExpandCollapse); } ```

It would make sense to be consistent with the auto-cleanup on stack creation.

Thanks! Sorry for the delay.

So, this issue is really old. Sorry I wasn't paying attention at the time. I'm not sure if this is still a need you have, after all this time. Even...
