I am not registered there, so I can't vote, I guess.
Generally I don't like reduce() HOF, because it generally leads to less
readable code (and often people use it only to compute a sum or product of
items), but this time it's a good enough usage.
You have forgotten to compute the average, as requested by the original article.
Regarding field access:
assert(r.field[0] == 2); // minimum
assert(r.field[1] == 11); // maximum
I've found that sometimes a shorter syntax is nice, I use d0, d1, etc:
assert(r.d0 == 2);
assert(r.d1 == 11);
(It doesn't replace the general [] access).
Yah, I had _0 but removed it. The plan is to use alias this to get rid
of field altogether so you write r[0], r[1] etc. but it turns out alias
this still has a few bugs.
