How to Build a Functional API—Julien Truffaut

[AdiantoWibisono]

I think the proposed product parser [27:39] is as powerful as the original production [25:58] using flatmap.
Since the for comprehension used when defining parser product is going to expand as flatmap.

Maybe I need to read up more about this, not even sure myself.

It appears you are partially describing an algebra of types and behaviors, but I didn't see the laws. Perhaps you could describe the relationships between a functional API and functional algebra. Thank you Julien.

Great presentation, BUT. In my opinion over engineering to the max. Keep it at basic algebras Try, Either, etc, in combination with good use of for comprehension will do the job just fine. Benefit is that every scala developer, beginner, medior, senior will understand it, without looking up what cats is.
