It seems to me, that std.experimental.allocator should work
with @nogc annotated functions if none of the allocators being

how this would work.
Are there plans for this?
It already mostly works in @nogc block:
- Mallocator and AlignedMallocator are @nogc.
- make() dispose(), shrinkArray(), etc are templatized function
so they infer @nogc.
- higher level blocks also infer @nogc.
example:
----
import std.experimental.allocator;
import std.experimental.allocator.mallocator;
import std.experimental.allocator.building_blocks.free_list;
struct Foo{}
void main(string[] args) @nogc
{
Foo* foo = Mallocator.instance.make!Foo;
Mallocator.instance.dispose(foo);
uint[] arr;
arr = Mallocator.instance.makeArray!uint(8);
Mallocator.instance.shrinkArray(arr,1);
Mallocator.instance.dispose(arr);
FreeList!(Mallocator,0,size_t.sizeof) fl;
auto p = fl.allocate(8);
fl.deallocate(p);
}

Initially it was not the case but it's been done latest months,
e.g in this PR:
