But you cannot use "foo" to denote the object and invoke the method at
the same time.  This is simply not possible.

How about defining a function class:

class Function
  attr_accessor :default

  def call(x = default, *rest)
    printf "x=%p rest=%p\n", x, rest
  end
end

# or even

f = Class.new do
  attr_accessor :default

  def call(x=default, *rest)
    printf "x=%p rest=%p\n", x, rest
  end
end.new

f = Function.new

f.call
f.default = 123
f.call

Cheers

robert
