i think you are completely wrong! FP way is to represent everything as
function, imperative way is to represent everything as algorithm.
there is no "natural thinking way", the only think that matters is
*when* student learned the appropriate concept. let's look - in my
college, the notion of algorithm was introduced at the 1st course
*before* any other programming courses. we even studied Turing machine
as an abstract algorithm executor

just imagine that we will learn Church's machine instead! and even
this don't required - notion of function is scholar's one! i'm pretty
sure that Haskell may be learned at 1st school class, together with
mathematics itself, and used as natural way to write expressions to

all the problem of learning FP paradigm for college-finished
programmers is just that their brains are filled with imperative
paradigm and they can't imagine non-imperative programming. it was
hard for me, too :)

we should change college programs to make FP programming available for
the masses
