in reply to The Concept of References

That looks like an explaination of pointers. It strongly suggests that you can do arithmetic on references, to get to the "next" memory location. I like this image:
+--------+ Alias: | $alias | ------------+ +--------+ | | \|/ +--------+ +----------+ +---------+ Variable: | $var | ----> | Variable | ----> | Content | +--------+ +----------+ +---------+ /|\ +--------+ +--------+ +----------+ | Reference: | $ref | ----> | Variable | --+ +--------+ +----------+
But that might be too much internals for some.
