All this thread is definitely above my head, but (assuming I understood 
correctly) removing the ability to use functions as table keys and 
unique identifiers looks confusing. Sounds as if functions would be 
degraded to "first class and a half" values.

Example: did I already call this function? I'd normally use "called[f] = 
true" to remember it. Or "called[f] = result" for memoization.
