> Chaining methods on classes But defining these is typically left to library authors in many languages. Writing your own Fluent/chaining interface isn't usually worth the effort. Where in these languages because any function is "chainable" and gets it for free a lot of programming ends up being chained pipelines. Anything where there is a logical workflow (a lot of programming) ends up being nice to read when expressed with pipes (i.e. do this, then this, then that, and finally return this). The pipe operator goes hand in hand with currying as well since you can complete some of the arguments before wiring the partial completed function into a generic workflow; a pattern that typically isn't be done with Fluent/Chaining methods on classes.
