I do not.

There isn't enough of a win to introducing allocators, unless you have 
knowledge of internals.

At which point you don't need to template your container upon the 
composable allocator. You'll have a dedicated one internally that isn't 
virtual.

This is one of my key take aways, don't pretend you need to customize 
the memory allocator to its usage if you don't know how it would be 
used. Go slower, go virtual, it'll keep you sane and allow you to build 
cool things.

Remember to profile. Not guess.
