Think of it logically, I'm not saying I *need* anything from boost.
But at the same time, we don't *need* anything from SDL either, as we
could recode it ourselves. And It wouldn't be as time consuming as you
might think, as we could and would cut out large portions of the
feature set that we just don't need.

And don't say its not time consuming to constantly be remaking the
same tuple code or making thousands of structs in just the same way.
Its very tedious. something that takes me a 10 minutes to do manually
I can do in two seconds with boost. Thats about a 99.67% time saving,
and that comes up more than once.

Using boost on the wide scale can save allot of time.
