It makes sense to add a dedicated section for pipe
in the docs, as it's a useful tool for doing custom things. It happens more often that I point out "you can do this with pipe
" and people didn't know that method existed.
Not sure I would call it 'debugging with pipe' though. It's useful for more than just debugging.
A "Pipe" page could be added to the "Transformations" section. This could showcase common patterns for using pipe. The schema assertion could be one, but a more important pattern is when you want to "name" some custom transformations and use them in a chaining fashion. We can include examples for Expr, DataFrame, and LazyFrame.
