Oh wait, I think I misunderstood your original question. Perhaps this is
closer to what you want:

	import std.algorithm;
	import std.array;
	import std.conv;
	import std.range;

	auto input = "48656c6c6f20776f726c6421";
	auto str = input.chunks(2)
	                .map!(digits => cast(char) digits.to!ubyte(16))
			.array;
	assert(str == "Hello world!");
