(Please don't top-post. I know it's the default in gmail. It's bad
list etiquette.)

That's actually not a problem at all! If msg_union is a global, it
just works out of the box. If it's a local, then just break it into
two lines:

local msg_union
msg_union = { ... }

Alternatively, if it reads better for you, you can write it this way:

local msg_union = {}
msg_union[0] = function(body) ... end
msg_union[1] = function(body) ... end
