Yes toHexString returns an array by value. This is not common in D APIs. As
more and more D code returns small arrays by value (to allow them to be @nogc
and increase performance), this kind of problems and bugs will become
sufficiently common that D programmers will be more aware of them and so they
will avoid them... :-)
