When importing a module D allows a modules functions to be brought into the
overload set by declaring an alias. Example

import std.ascii;

bool isLower(bool c) {
    return true;
alias isLower = std.ascii.isLower;

Templates should allow for the same behavior:

import std.range;
import std.algorithm;
import std.traits;

bool isSorted(alias less = "a < b", Range)(Range r) if (isStaticArray!Arr) {
    return isSorted(r[]);
alias isSorted = std.algorithm.isSorted;
