fails first because of missing import
import std.experimental.allocator : allocatorObject,
theAllocator;
and then, when adding this import, it fails again with the error

Error: template instance `FreeList!8` does not match template

Why is this example missing the `ParentAllocator` template
parameter and what is the preferred type for `ParentAllocator`?
ParentAllocator can be anything preferred types don't really make
sense in a composable design, but it's probably best to go with
something like GCAllocator, Mallocator, (Mmap, Sbrk etc.)
something that asks the system for more memory for the last
fallback so you don't run out of memory.
