I don't remember. Tuple precedes Bind in the formal review schedule, so this 
is not the reason. I probably didn't consider Tuple stable enough to build 
on it. In those times, compilers such as MSVC6, Borland 5.5, HP aCC 3.x (?) 
were still important and had interesting limitations. It's easier to fix a 
compiler issue if everything is self-contained.

One case where this paid off recently is when I added the space optimization 
to _bi::listN at Doug Gregor's request, to make placeholders not take up 
space in a bound expression. This optimization could've been more difficult 
with a tuple-based implementation.
