The title.

Seriously though, I think that "fluent" interfaces are being re-branded as "monadic" -- I assume because you're creating or piping around bound state and unwrapping/re-wrapping it with the various constructs.

It doesn't even seem to be piping anything around though. The result of the filtering certainly isn't getting piped anywhere.

If I wanted something like this I'd probably just reach for pampy and use pattern matching. Which still isn't "Monadic".

The result of the chain is retained in the `value` property as described in the documentation. Mapping and composition are supported.
