The idea of declaratively describing transformations of data seems very exciting to me. I haven't experienced anything that lives up to the excitement though.

The idea of declaratively describing transformations of data seems very exciting to me. I haven't experienced anything that lives up to the excitement though. I feel a bit underwhelmed by these examples. Seems a bit to imperative, an enhancement of underscore. I want the declarations of how data representations relate to each other to be separate from the "how" in how to transform from one format to another. Probably something inspired by lenses (1). "Lenses are the XPath of _everything_." (2).
