After 2 hours of brain breaking (as D newbie) I have come to:

uint_array.map!(v=>"%x".format(v)).join(", ")

Why 2 hours? Because I have started with 'joiner' function and
aftewords found out the 'join'.
To my mind there is more simple form for this task in D (about
formatting).
sure ;-)
import std.stdio;
import std.format;
void main () {
uint[$] a = [42, 69];
string s = "%(%s, %)".format(a);
writefln(s);
}
Accepted.
Is it really needed to call 'writefln'? I mean 'f'.
