+A heap is an abstraction for a set of objects of possibly different types which can be referenced by pointers.   `$alloc` adds an object to the heap and returns a pointer to that object.   The object can then be read or modified using the pointer.  Example: C code that mallocs 10 ints
 {{{
 int * p = malloc(10*sizeof(int));

 More generally, if the type of objects being malloced is not known, or changes dynamically, one could define a general "object" type...
