so if you just set a variable in the node scope you can use those in
extlookup as I described - much simpler than writing an entire new type
of function.
And combine this with the optional paramter to extlookup that let you
specify a search-first file and you get additional key/dimension you
wish.
Still, just write the functions you need - sounds like you know exactly
what you want and its quite specific so just impliment it :)
If its good and all, you can share it on forge.puppetlabs.com
