I propose a new paradigm:
Objectional programming
Functions don't return
Everything must be done by side effects
Global state mutation is inheritance
Every call is non blocking and spawns a new thread
???

I fundamentally disagree with the idea that these are competing strategies.
Just like walking doesn't really compete, like at all, with flying in an aircraft, Functional and Object Oriented Programming are at their best when you use whichever approach makes sense for a given situation and in any reasonably complex software that means your code should be full of both.
OOP is really good at the high level structure of your software as well as efficiently storing data. FP is really good at business logic and algorithms.
Also, I take issue with the claim that OOP is all about "objects". It's also about classes. In fact I'd argue classes are more important than objects.

I'll just stick them together.

If your program functions, it's functional.

Article is pretty lame. Not exactly wrong but doesn't convey a clear understanding.
replies:
Functional is so sexy and I try to use it where I can but I work in a real time environment where the microsecond price of copying immutable data is just too damn high. Still it's useful in places that aren't time critical, especially if the problem is complex.
