But that's not a good thing, right?

My experience with Drupal so far has been limited to the API, so I don't know
how things like this are handled in core. But I do know how much I used arg() in
my first attempts, and how much I would regret it when having to revisit that
code. It is faintly similar to the "Accumulate and Fire" antipattern. If the
help hook could be improved to the point where it doesn't need any workarounds
in core...

Also, here's one wild idea that I thought of when I read the other three:
Would it be at all sensible to pass the menu key ("node/%/edit") and a separate
array with all the variable values, in order: ($nid)?
