util.datamapper: Don't include empty unwrapped arrays Since there is no way to distinguish an empty such array from a zero-length array. Dropping it seems like the least annoying thing to do.

local xpcall = xpcall;

if select(2, xpcall(function (x) return x end, function () end,  "test")) ~= "test" then
	xpcall = require"util.compat".xpcall;
end

return {
	xpcall = xpcall;
