Disclaimer: my level of expertise in the field is approximately zero.

Having said that, from what I've heard, it seems that indirection and virtual
call cost can be quite noticeable with simple allocators (e.g. region
allocator). Could we have an allocator template argument that would default to
IAllocator, so that one gets all benefits of runtime binding by default, but
still can get static binding if it is required?
