+1 (as one of the non-newcomers who prefers plus)

me too.

frankly, the | is obscure to most of us. And it started as "bitwise or", and evokes the __or__ magic method -- so why are we all convinced that somehow it's inextricably linked to "set union"? And set union is a bit obscure as well -- I don't think that many people (newbies or not) would jump right to this logic:

I need to put two dicts together

That's kind of like a set union operation

The set object uses | for union

That's probably what dict uses -- I'll give that t try.

Rather than:

I need to put two dicts together

I wonder if dicts support addition?

I'll give that a try.

so, I'm

+1 on +

+0 on |

if | is implemented, I'll bet you dollars to donuts that it will get used far less than if + were used.

(though some on this thread would think that's a good thing :-) )
