But the "+="(or "+") operator can be quite ambigious
in the context of table, even for just default
behaviour.

t={1,2,3,4}
d={5,6,7,8}

t += d

should I get {1,2,3,4,5,6,7,8} or {1,2,3,4,d} as I see
adding two table together(i.e. extend) is just as
natural as adding two number together. t+d =
{1,2,3,4,5,6,7,8} is the default behaviour in python
list.

that is also true for {1,2,3,4,d}. As d in this case
is being treated just as another object putting at the
end of a table.
