Slop::Options

Fetch an Option object. This method overrides Array#[] to provide a nicer interface for fetching options via their short or long flag. The reason we don't use a Hash here is because an option cannot be identified by a single label. Instead this method tests against a short flag first, followed by a long flag. When passing this method an Integer, it will work as an Array usually would, fetching the Slop::Option at this index.

@param [Object] flag The short/long flag representing the option @example

opts = Slop.parse { on :v, "Verbose mode" }
opts.options[:v] #=> Option
opts.options[:v].description #=> "Verbose mode"

@return [Option] the option assoiated with this flag
