The sole purpose of that is to get a textual sufficiently unique ID for
the thing?  (I'm guessing...)

You could auto-generate IDs and weaktable them.  Is that good enough? 
That avoids tostring() altogether.  (Could also be much more readable 
than random hex digits.)

Another fun question:  If a table (or userdata?) is freed and another 
one is created later that has exactly the same address, will whatever 
you're doing break, or will it still work?

(But yeah, I've also added/used a debug.tostring() before... ^.^)
