Subject: Fun with setter functions

I have a setter function in a class that I would like to pass additional  
arguments to, so I can do some addtional calculations if required.

My first crack at this was to do something like...

....
def variable=(value, options=nil)
  @variable = value
  do_something_cool if options == :flag
end

Here's the only problem, how do you pass the options?

object.variable = value, :flag
results in
[value, :flag] being passed to the function.

I see a couple of work arounds.
1. send works, but is ugly  object.send('variable=',value,:flag)
2. rewrite variable so that it expects an array and just unpack stuff  
from the array

Any other solutions I may have overlooked?
