There's also this one:

def foo opts={}
  if opts[:some_parameter]
    do_something_with_parameter
  end

  if opts[:some_other_parameter]
    do_something_with_other_parameter
  end
end

foo :some_parameter=>123, :some_other_parameter=>'abc'

This is used as a substitute for 'true' named parameters. It is mostly
useful if you need to take a moderate number of entirely optional
parameters.
