Accessing Type Metatables Lua -

-

its getmetatable can access metatables of several types:

getmetatable("") getmetatable({}) getmetatable(newproxy(true))

however appears though cannot metatable of other types (functions aside). there appears no way access metatable of numbers, booleans, or nil.

i wondering if 1 able access metatable of entire table type. able this:

({}) + ({})

numbers, booleans , nil have no metatable default (hence getmetatable returning nil). can give them 1 debug.setmetatable though.

there no common table metatable. (and same userdata (at least of heavy variety))
