Today's Zen question: What is the meaning of == ?
The meaning of the == for reference types (any Capital-letter type in Java such as String) is: exact equivalance of pointer values, i.e. same location in memory.
Any call to cons(), list(), or new allocates brand-new storage, different from any existing storage that might be pointed to. Since there are two calls to list(), each one gets its own brand-new storage, and they are guaranteed to be in different locations.
