I meant "list" in a generic sense.  (I actually did start with a  
mpl::list, but switched to a mpl::vector because some operations  
weren't supported otherwise.)  I think my needs are "impractical";  
the numbered-form lists stop at around 50, and I'll need to go to  
nearly 70 (until 128-bit types come forth).  How do you concatenate  
lists, hopefully so I wouldn't have to change the code that expects a  
"normal" sized list?
