starting with (let [f# ~f] ...). Better still, ask why this is a macro
at all. This should really just
Reducers don't enter into the picture at all: this code is just as
broken with clojure.core/reduce and clojure.core/map. The immediate
problem that Kevin is trying to draw your attention to is that you are
calling (reduce max (map my-fn coll)), where my-fn sometimes returns a
number, and sometimes
You will get better results from a game-programming forum, or indeed
from a google search for parallel alpha beta than from a bunch of
clojure guys with no particular experience in your problem domain.

Evaluating function literals is not intended to work; that it works

Sentence one. Don't do it that way: namespaces are not very good hashmaps,

(a) There's no reason for this to be a macro at all: you don't need to
prevent evaluation of anything, and you don't need to transform any
syntax. Just write a function: (defn asdf [ {:keys [a]}] (println
(comp (partial + 1) a)))

Indeed, there's no need for anything to be a reader macro, except

Vote to close as not a real question. The signature of
java.util.Collections/sort hasn't changed since 1.5, when generics were
introduced, and it should still be basically compatible with what it was
when it was introduced in 1.2.
