Actually you don't even need a new type compressed_tuple.  You could  
put this functionality straight into tuple.  It'd be a royal pain to  
do for tuple sizes greater than 3 or 4 though.  Dave, how many empty  
members do you find yourself glomming together?  I often have several  
potentially empty members but usually have at least that many non- 
empty members to spread them around on (I have one example where  
wanted to glom two empty members onto a non-empty member).
