I obviously lack of culture, thanks for the precision.

What you think it is like will depend on how you approach it.

Exactly, each paradigms I have learned (OOP, FP, Logic, Actor, Data-Flow)
seemed to be a giant mess until I found a good approach and see a big and
coherent unit.
I miss a approach to broadcast it for FP.

That's currently that we tend to do, but these are too "toy examples", they
doesn't stick to the day-to-day problems.

Good hint.

I totally forgot the last one, but I think it doesn't emphasize enough on
the type part.
