...which can be a little counter-intuitive to the uninitiated, I presume.
If you want to be a little more abusive in terms of puppet style, but
put emphasis on expressive error messages, include this in each class:
if defined(Class["a"]) or defined(Class["b"]) or ... {
fail "including more than on of class a, b, ... is forbidden"
}
Again: This is terrible style, but it'll do the job (and subjectively,
the canary resource strikes me as a bit of a hack itself, too).
Cheers,
Felix
