A suggestion in D.learn shows me that sometimes
std.functional.binaryReverseArgs is an acceptable solution for the terminal
writefln (but it can't be used for intermediate printing):


import std.stdio: writeln, writefln;
import std.range: iota, transversal;
import std.algorithm: map, reduce, max;
import std.functional: binaryReverseArgs;

void main() {
    immutable txt = ["Line one", "Line 2"];

    txt
    .map!q{ a.length }
    .map!((s){ s.writeln; return s; })
    .reduce!max
    .iota
    .map!(i => txt.transversal(i))
    .binaryReverseArgs!writefln("%(%s\n%)");
}
