Its not Ruby related, but you might want to look at "Starting Forth" and
"Thinking Forth". These are classic texts, and the terminology
(buzzwords) are not the same as today, but still a pleasure to read.

Starting Forth: http://home.iae.nl/users/mhx/sf.html
Thinking Forth: http://thinking-forth.sourceforge.net/

or if you want to look at a quick DSL example, take a look at this:

Maybe someone can translate this example to Ruby sometime. It seems so
natural in Forth though. Its weird how sometimes largely forgotten
things still have the power to teach us :)


HTH,
