Lua desperately needs a form of optional static typing, not those

Since I used Lua for the first time, (~ 7 years ago,) my "would be
nice if" list includes a "freezeType(val)" function that would
constrain future assignments to val to its current type. Of course, if
the type is table, that is a very weak limitation.
[ What about a freezeValue() ? ]
if getmetatable(t).__index[k] then error() end rawset(t,k,v) end})
