No, I actually meant "declarative" .... See this reference:

Quote:

In computer science, declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow. Many languages applying this style attempt to minimize or eliminate side effects by describing what the program should accomplish, rather than describing how to go about accomplishing it. This is in contrast with imperative programming, which requires an explicitly provided algorithm.

Declarative programming often considers programs as theories of a formal logic, and computations as deductions in that logic space. Declarative programming has become of particular interest recently, as it may greatly simplify writing parallel programs.

Common declarative languages include those of regular expressions, logic programming, and functional programming.

I see now that Ruby is not classified as a "declarative programming language", List of programming languages by category.
