No, there isn't.  However, often using a hash as argument solves this
problem:

class Foo
  def initialize(h={})
    h.each {|var,val| send("#{var}=", val)}
  end
end

Foo.new(
  :caption => 'Click me',
  :color => :orange,
  :size => 42
)

With a bit more code you can even have default values.

Kind regards
