I'd love to here more opinions on whether this is a worthwhile optimization. 
The speed demon on my right shoulder says it'd be great to cover a relatively 
common case without allocating memory, but the devil on my left shoulder is 
poking me in the neck to remind me of the 33% increase in the size of 
boost::function objects.
