I'm trying to overload the '<=' operator in a class in order to use it for 
assignment:

class Blah
  def initialize(value=0)
    @value = value
  end

  def <=(new_val,time=0)
    puts "time is: #{time}"
    @value = new_val
  end
end

a = Blah.new
a<=5      #prints: time is 0
a<=(8,10) #results in parse error, doesn't like the ','

So apparently you can't have more than one argument for an overloaded 
operator (it actually kind of makes sense) - is there any way to do this?

Other than:
class Blah
def assign_at(new_val,time=0)
  puts "time is: #{time}"
  @value = new_val
end
end

a = Blah.new
a.assign_at(8,10)

....it just isn't as nice.
