Re: [Boost-users] bind doesn't use tuple

why doesn't bind use tuple (internally)?

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.
