Subject: Passing args from within method_missing

Hi,

I have an hash of code blocks(procs?), @styles, and am trying to call  
these using method missing. Problem is, some take one argument, and  
others take two, and I can't seem to pass args to them without if  
being passed as an array

Here's the method_missing code

   def method_missing style_type, *args
     case args.size
       when 1 : @styles [style_type].call(args[0])
       when 2 : @styles [style_type].call(args[0], args[1])
     end
   end


I'm sure there's a way for me to get rid of the case statement, but  
if I try
@styles [style_type].call(args) it just gets sent an array.

Question is, how do I send the contents of the args array?

I realise I should probably have a means of dealing with a genuine  
method_missing. What's the 'ruby way' of doing this? if I call  
method_missing again, wont I end in a recursive mess?

Is this making any sense?

Cheers,
Dave
