Example:

import std.format : format;

string hex = format("%(%2x%)", "Hello World");

import std.stdio : writeln;
writeln(hex);

A bit of explanation: %(  %) is a range formatting specifier, and 
basically means "format each element of the range with the format 
specifier between these two symbols". In other words, it's the 
equivalent of "Hello World".map!(c => format("%2x", c)).joiner.
