+      The C++ STL allocator model has various flaws. For example, they are
+      fixed to a certain type, because they are almost necessarily required to
+      be templates. So you can't easily share a single allocator for multiple
+      types. In addition, you can only get a copy from the containers and not
+      the original allocator object. At least with C++11 they are allowed to be
+      stateful and so can be made object not instance based. But still, the
+      model has many flaws. Over the course of the years many solutions have
+      been proposed, for example EASTL. This library is another. But instead of
+      trying to change the STL, it works with the current implementation.
