Functional PHP Extension

hi wired, thanks for the feedback:

yes, i downloaded the code, read thoroughly, read the graham thing on power=succinctness, studied the wikipedia page on functional programming and read one of the tutorial pages linked from the wikipedia page.

i understand the theory. i know many of the concepts are available already in PHP (c.f., call_user_func(), create_function(), and the ability to assign functions to variables which PHP calls variable functions variable functions in php manual:

i see how the FP library wraps up those disparate elements into a package that approximates FP in toto.

i see in general how the FP coding approach is strikingly different from a procedural and the OO approach.

what i am missing is a concrete example of how adopting this approach will:

a) make me a better/faster/more efficient programmer
b) make my code more expressive and "succinct" without losing clarity
c) illuminate my current CI projects - especially this one because this is the "language" we all use here (in addition to PHP of course)
