Yes. I'm getting used to that -- it's a bit of a shift, because I'm
used to exceptions being *exceptional* -- as in, not a failure mode
you would expect to see happening. So for instance, I wouldn't expect
to get an exception for EOF, because that's not exceptional, that's
virtually guaranteed to happen whenever you interact with files. I am
gonna have to retrain a bit.

Interesting! That may take me some getting used to.
