With regard to __setindex, I was just thinking this morning about the
costs associated with creating read-only tables and thinking that it
would be worth benchmarking the approach of using a stub userdata:
ud.mt = { __index = read-only-table }
And using a proxy table:
{}.mt = { __index = read-only-table, __newindex = error-function }
__setindex would be the simplest option but would then need to be
benchmarked for its effect on all table assignments.
