Yes, of course I know this - I'm sure many people know this. What Angular 2 calls a "pipe", though, doesn't refer really to the piping of the data (though of course it also uses a vertical bar), but the actual thing that's receiving/processing the data. Their previous name of "filter" was probably better, except for use-cases where there was no filtering being done.
