It's not really that meaningful, except where you build a more specific type 
based on 'array', designed for mathematical work.

But if the language allows it, then it would quite likely be to allow list 
operations in general, so that in a = b op c, then 'op' is applied between 
all corresponding elements (as in languages such as "K", but without quite 
such an obvious syntax...)

That's far more useful. But better to use a symbol other than "+" I think.
