I also need entirely static pools that allocate memory at *compile* time via template parameter.
I use this kind of pool as the basis for memory allocation in embedded microcontroller projects.

So I would actually need one-shot allocation (as you describe) as well as compile-time allocation.

I have always written my own pools for this. I might be nice to get one *off the rack* from boost.

Good luck.
