Which sort of *makes* my point: they're *two separate modules*.
They're not 2 different versions of the same module.

<sigh>
*You* are suggesting that.
*I* am suggesting that you deduce it from the *name*. I am saying that

because you are *overloading* the version number, giving it semantics
it should not have.
