I am busy, but I hated to see this get the usual silent treatment. :-)

Actually, I meant "@ = wildcard" - this would be a general convention
and wouldn't just expand to "lan" in all cases, it would expand to
fit whatever was necessary to allow the fall-through case to work,
be it for an ethernet card or something else (how about specific
vs generic route entries, for example?).
But I still like option #2 better, so it's also probably not worth
debating overmuch. :)

Creeping featurism will expand this set of event-response sequences,
I'm sure. :-)
Also, if you think about it, the system's initial boot is also sort of
an "event" of sorts - I'm sure you could generalize this to the point
of absurdity, and it might not even be that bad of an idea.

POC?

I thought you'd just expand the target variable and check it
for NULL-ness (""). If it expands, you pass it to eval. If it
doesn't, you move on.
