The subroutine addresses #1, but not 2 or 3.
It does address 2. The list is generated once (wherever) and only passed to
the subroutine once. No regeneration required. It's exactly like your "all but
illegible" solution, just factored out and deuglified.
Since I don't understand what you mean by 3, I can't really judge whether it
addresses it. But I *can* say it addresses it exactly as well as your "all but
illegible" solution did.
Also, there's a #4: modified state, which is hinted at but not really
covered by #3.
4 is not possible using the pointy sub syntax in any form, since all params to
pointy subs are always constant aliases.
