Re: Metatables and environments going wrong in Lua5.2

[张睿 <zrui16@...>]

m2.x = 2

--this operation (settable) is raw, i.e. no metamethod is called and a new key “x” is created in m2, not m2.variables.

If you want m2.variables.x to be changed, use a __newindex metamethod for m2 (again, not m2.variables).
