/* These macros provide a K&R/C89/C++-friendly way of allocating structures
with nice encapsulation. The XDELETE*() macros are technically
superfluous, but provided here for symmetry. Using them consistently
makes it easier to update client code to use different allocators such
as new/delete and new[]/delete[]. */
