Wow! I would have never imagined that such a simple basic question would generate so much dialogue.
It turns out that I was trying to create a key with 18 components and I got rejected. Note that this was a pretty contrived case (I'd never actually design a database like that :-D) in a temporary table whereI was hoping the additional key elements might improve performance.
Surely now it is something I'll never forget either.
Thanks to all for stopping by and commenting!

My thought question: Have you ever been told that your query runs too fast?
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
