There was a typo in my code: `ipairs` should have been `pairs`.
Here's the fixed version:

``` lua
if PANDOC_VERSION <= {2, 18} then
  local mt = debug.getmetatable(pandoc.Pandoc{})
  mt.__concat = function (a, b)
    local result = pandoc.Pandoc(a.blocks, a.meta)
    result.blocks:extend(b.blocks)
    for k, v in pairs(b.meta) do
      result.meta[k] = v
    end
    return result
  end
end
```
