Only infinite rate is valid?

I think you are missing some braces here, but I think an early return for illegal input would be clearer in any case.

Only a finite rate is valid.

Oof. Somehow my braces got removed.  The logic here got reversed due to an earlier review by Darin, but I could reverse the logic here with a `!(...)` and switch to an early exception.

An extra empty line?

Nit. Maybe it is better to check whether 'internals' is available at the beginning of the test?

Ditto.
