Observe, in the code snippet below, that no fewer than 27 subtly different aliases have been created for the same chunk of memory...

Semantics/Syntax: The @ sign instructs the compiler to have the variables named `varsc`

and `vars`

share storage much like C's `union`

construct. The `symbolic`

keyword acts like a macro definition.
