You are right. May be i am to much lua beginner to see the benefit of your
approach compared to
tablevar = setmetatable({}, getmetatable(tablevar))
The only difference i can see is, that table.clear() would do (parts of)
the _gc job sooner.
I explained this in an earlier post -- the difference is if there's
more than one reference to the table hanging around. Making a new
table in Lua code and assigning it to the variable leaves those other
tables unaltered, which is almost surely NOT what you wanted to do.
