Normally I'm happy with the GC containers in D, they work well and suit my use.

I have a few uses that would benefit from allocation in memory arenas or local stack based allocation. Looks like std.experimental has allocators for those use cases.

But I can't find any containers to make use of those allocators. The built in ones use GC managed memory, there are std.container but they appear to use malloc/free which again is useful but not what I'm looking for.

I'd like resizeable arrays, hashmaps and strings that I can allocate using an allocator?
Am I missing something in the standard library, or a way to use the existing ones, or is it just that nobody has implemented this kind of thing yet?

It uses the older design for allocators (dependency).
