If you invert it, it works better:
port { '22/udp': label => 'telnet' }
Or something like that.
I was looking through some heinously old (pre-Puppet code) somewhere and this
is how it was solved, and I realized that while it's a touch ugly and would
tend toward duplication (e.g., the udp and tcp cases would be duplicate here),
it does solve the problem, which is more than I could do previously.
However, the multiple primary key solution is definitely actually the right
one, so if you can figure out how to make it work (directly CC'ing Markus in
hopes he'll chime in) that's definitely the "best" option (where "best" takes
no account of effort, just result).
