How Hashes Really Work (O'Reilly)
Abhijit Menon-Sen
explains
hashing in the context of Perl.
"It's easy to take hashes for granted in Perl. They are simple, fast, and they usually "just work," so people never need to know or care about how they are implemented. Sometimes, though, it's interesting and rewarding to look at familiar tools in a different light. This article follows the development of a simple hash class in Perl in an attempt to find out how hashes really work."
