Yeah, if your functions return the same error it's quite difficult to use the "else" pattern. I also dislike the fact that the error handling is not near the function that provokes it, but in a separate block, so you have to remember which function in the pipeline returns which error. I've never written a with-pipeline with more than 4-5 calls, so it's been easy to avoid its limitations, but I can understand it's not optimal if you're writing complex stuff.
