It sounds like, if "%" is still going to be kept (rather than just
outlawed), then its default behaviour should be changed to reflect its old
usage. Ie:
    local x
    f = function() return %x end

should simply be a shorthand for
    local x
    do
        local x=x
        f = function() return %x end
    end
