Would it be better, even if seemingly uglier (to me) to use
'ssn123-45-6789' instead of simply '123-45-6789'
which would make the digit string into a legitimate Lua name.

Actually, it wouldn't, ssn123-45-6789 is not a lua "name":
% lua
Lua 5.0.2 Copyright (C) 1994-2004 Tecgraf, PUC-Rio

ssn123-45-6789 = 3

stdin:1: `=' expected near `-'

ssn123 = 3
print(ssn123-45-6789)

-6831

Wow, I just got bit by another assumption on my part. Oops. :)

Obviously I wasn't thinking. Nor have I attempted such. I would definitely have to remove the dashes to make such valid.

Thanks for pointing that out to me.
It helps in training my mind to spot thinking errors.
