Maybe something like:

void main() {
     // Those look like lots of imports but most of those are very 
common anyway
     import std.digest: toHexString;
     import std.stdio: writeln;


     string s = "Hello world!";
     (cast(ubyte[]) s)    // We want raw bytes...
         .toHexString     // ...convert them to hex...
         .writeln;        // ...and print.
}
