I don't see how you can't. Other standard methods take variable 
arguments: __init__, __new__, __call__ come to mind.

I'm not sure what you mean by "too special". It's no more special than 
any other special method. Do you mean the use-case is not common enough? 
I would find this useful. Whether enough people would find it useful 
enough to add yet another special method is an open question.
