Allocators and Containers

[Minty Fresh via Digitalmars-d]

A lot of the usefulness of the std.experimental.allocators module 
is lost because no other part of the stdlib actually ties into 
the functionality provided by it.

For example, the Array type defined in std.container relies on 
malloc() directly, so if you wanted to use a type to replace 
built-in arrays with a custom allocator, you'd need to implement 
your own container type.

Would it make sense to allow the std.container types to accept 
IAllocator instances, and to allow custom allocators? (Using 
Mallocator by default.)
