Losing the magic

Isn't this the situation from which Rusgocamkell will save us?

Sorry. Couldn't resist the snark. Run-time-ish methods to ensure compatibility likely are good at the correct abstraction points. I've used eight-character strings to detect (integer) endianness as a trivial example. Not zero terminated.

And losing magic for openness isn't bad necessarily. Just a tad sad for ex-wizards.
