Though if we're worrying about optimization, it would be nice to recognize
that if given something like:
for i, x in ipairs{ "a", "b", "c" } do
--
end
Then the constructed table can be lifted out as a constant.
Of course, that assumes that one knows what ipairs does and that it doesn't
modify the table in some way which of course we don't know...
