This Python program finds the number that has the largest minimum prime factor:
def decompose(n):
result = []
i = 2
while n = i * i:
while n % i ==

In dmd 2.064alpha you can't use minPos on a byKey range:
import std.algorithm: minPos;
void main() {
int[int] aa = [1: 2];
int m1 = aa.byKey.minPos!((a, b) = a

I still think mins()/maxs() are useful. But years after the original proposal
an API change in max/min is now problematic (unless you want to introduce

In Haskell the reduce!min and reduce!max are named minimum and maximum.

Another example of the usefulness of maxs/mins:

Another example, compared to using minPos():
import std.stdio, std.algorithm, std.array;
void main() {
string[] data = [red, hello, yes, no, roger, bud];

The code that uses minPos() also leads to a possible bug (a real bug I have
found in my code), shown here:
import std.stdio, std.algorithm, std.math, std.range,

(Maybe I'd like an annotation to tell the compiler that data is an an Input
Range, unlike iota() that map is iterating on.)

A max/min with a comparing function is present in the Haskel standard library
too, named maximumBy:
import Data.List
import Data.Ord
longestWord words = maximumBy

The examples hopefully show how much useful are the new max/min.
This is part of the pivoting part of a LU decomposition algorithm:
T imax = mat[j][j];
int nrow = j;

Two more usage examples of the improved max. This program finds the longest
common subsequence with a recursive algorithm:
import std.stdio;
T[] lcs(T)(T[] a, T[] b) {

Another example to show why a better max() is useful. The task is ot show how
the number less than 1000 which has the longest hailstone sequence. For the
hailstone see:

Aside the posted comment, I rather support this proposal.
Have you ever called an external func for min(a,b) or sum(a,b)? (lol ;-)
So, according to me, what we

Aren't they niche domain tools?
The opposite is true. Functions and HOFs like max, min, sum, maxs, map, filter,
reduce, and so on are basic
