My database library SqlTable does exactly this, to prevent it's internal state information from colliding with the keys of data within the database. It hasn't caused problems in Lua 5.1 through to 5.3, so it at least works well. If it's actually a good idea... I don't know.
I use
local KEY = {}
local foo = {[KEY] = {stuff}, your, data, here}
this will never conflict with something like a database. it also avoids
going through a function call to do a metatable lookup and stuff. but it
does get in the way of pairs, so if pairs is important for you then I
guess you can't use it.
