Hello Ruben, I think this just refers to the fact that parsers can be combined using the lenses provided by the library. Gabriel Gonzalez[1] wrote "pipes-parse-3.0.0 introduces a new lens-based parsing mechanism." So it doesn't seem to correspond to a globally known pattern.

Dear Cafe

I've reading the tutorial for pipes-parse, and I got some references that it supports lens-based parsing. I know lens, yet I don't really know what is that about. Also looking in google doesn't get any detailed blogpost. Can anybody help me out on what is this?
