Functional PHP Extension

@sophistry -- Thanks for the article. It was very interesting, very academic, and not very pragmatic. I agree with your point above.

The term showed up! "Referentially transparent" is the term that is used to broadly describe the attribute I attempted to describe in my post above. Gosh, I'm old. I don't think I've read that since grad school about the time that paper was written!

To solidify your point about 'you can not just drop this library in...', here is another resource:
http://www.cs.nott.ac.uk/~gmh/faq.html
Check out the programming languages, when they were written and the descriptions of support, etc.

We're using a 4GL (if anyone remembers that term) that is purposely abstracted from the bowels of the 'system' so we don't have to worry ourselves over set theory or the implementation of this:

Code:

integrate f a b = integ f a b (f a) (f b)
integ f a b fa fb = cons ((fa+fb)*(b-a)/2)
(map addpair (zip (integ f a m fa fm)
(integ f m b fm fb)))
where m = (a+b)/2
fm = f m

in our web application for goodness sake.

I realize many of you are computer science students who are studying this stuff and are mezmorized by the sheer possibilities offered. I'm only suggesting that PHP+CI is not the best place to explore those possibilities.

@JomongKad -- Thanks for bringing this discussion and rekindling some very long lost thoughts. These days I spend more time actually creating solutions than thinking about what might be a better way of creating solutions.

Regards,

Randy
