OO is outdated. D uses the range-based idiom with UFCS for chaining
operations in a way that doesn't require you to write loops yourself.
For example:
import std.array;
import std.algorithm;
import std.conv;
import std.range;
// No need to use .toStringz unless you're interfacing with C
auto hex = "deadbeef"; // let compiler infer the type for you
auto bytes = hex.chunks(2) // lazily iterate over `hex` by
digit pairs
.map!(s => s.to!ubyte(16)) // convert each pair to a ubyte
.array; // make an array out of it
// Do whatever you wish with the ubyte[] array.
writefln("%(%02X %)", bytes);

Wouldn't it be more accurate to say OO is not the correct tool for every
job rather than it is "outdated". How would one write a GUI library
with chains and CTFE?
But you could with signatures and structs instead ;)
