First of all, I would like to thank Rich and this community for
producing such a pleasurable language, and for putting up with with
all the unpleasant nit-picking of new users. That being said...

I am curious as to why the function parameter is specified before the
collection parameter in map/reduce. I have never used a lisp before,
and may not be aware of idiomatic style, but it seems to be the
convention elsewhere in Clojure (assoc, conj, .method calls, etc...)
to have the "altered" data structure be the first parameter.

Would this not allow mixing map into a threaded expression:

(-> [1 2 3]
 (map inc)
 (assoc 0 4)
 (reduce +)
 (conj :anotherthing))

Perhaps this style is rare in practice? Certainly it is easy enough to
write a custom map/reduce which acts this way, so I suppose my
question is mostly philosophical.
