--- Comment #7 from Martin Nowak <code at dawg.eu> 2014-01-24 21:23:16 PST ---
Haskell has a function call flip for this.
http://hackage.haskell.org/package/base-4.6.0.1/docs/Prelude.html#v:flip

It turns a function taking (a, b) into one taking (b, a) instead.

In phobos this is called binaryReverseArgs.
http://dlang.org/phobos/std_functional.html#.binaryReverseArgs

So one can use
    rng.binaryReverseArgs!(reduce!fun)(seed);

Maybe we could rename it to flipArgs to make it useable?
