Subject: [ruby-core:49782] Re: [ruby-trunk - Feature #5010] Add Slop(-like) in stdlib and deprecate current OptionParser API

I agree with Rodrigo. If I have to use an option parser, I don't want to 
waste time shopping around.

Also, if no option parser outside optparse gets significant traction 
outside the Ruby standard library, this means that none of them is 
significantly better than the current one for a significant percentage 
of Ruby users.

I think the best thing is for the people who really care to get together 
and merge their work, and then come here with a replacement proposal.

Regards,   Martin.

If there ((*has*)) to be something more, then only a very simple library like CLAP (https://github.com/soveran/clap/blob/master/lib/clap.rb) extending ARGV itself, makes the most sense to me.
