Validations are passed options

[pboling]

Documentation says this should work:

string :style, default: "flat", validator: ->(v) {
  raise "style can't be empty" if v.empty?
}

But I'm getting an error with that construction:

     ArgumentError:
       wrong number of arguments (given 2, expected 1)

Instead what works is this:

string :style, default: "flat", validator: ->(v, _options) {
  raise "style can't be empty" if v.empty?
}
