Good. Having waded through one of the threads on p5p just a minute ago,
I'm not willing to guarantee this. In fact, I'm willing to explicitly not
guarantee this. If we want to compare two frozen structures, string
equality is *not* the way to go. Each freeze could, theoretically, choose
a different freezing method yet still represent the original.
This is a Good Place for a black-box comparison op, which string equality
definitely is not.
