I'd suggest picking another battle to fight. This one is arbitrary and unimportant. It's not a battle you can win. You're focusing the blame for bad tutorial examples in the wrong place anyway. The use of foo as a variable placeholder is no difference than using x in mathematics to represent a reference to an arbitrary value. There are a lot of people that also have trouble with this abstraction and find algebra difficult to grasp. That does not mean that math instructors should stop using x, y and z as abstract placeholders to unknown values in a equation. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
