It's unfortunate that most people who praise Ruby as being this groundbreaking language in terms of features and usability neglect to look back 30 years at its roots in the smalltalk language. In fact, the smalltalk syntax to do the same thing is surprisingly similar.
1 to: 10 do: [:x | x printNl]!
For those of you unfamiliar with smalltalk, I'd really urge you to look into it. Squeak is a very mature implementation http://www.squeak.org/. In either case, you're right the syntax is powerful and beautiful, and in my opinion its a real shame that it has taken 30 some odd years for people to realize its potential. Even the java language is moving in towards adding closures as a language feature http://www.javac.info/ .
