I'd like to make a plea to people: I get it, there is now significant opposition to using the + symbol for this proposed operator. At the time I wrote the first draft of the PEP, there was virtually no opposition to it, and the | operator had very little support. This has clearly changed. At this point I don't think it is productive to keep making subjective claims that + will be more confusing or surprising. You've made your point that you don't like it, and the next draft^1 of the PEP will make that clear. But if you have *concrete examples* of code that currently is easy to understand, but will be harder to understand if we add dict.__add__, then please do show me! For those who oppose the + operator, it will help me if you made it clear whether it is *just* the + symbol you dislike, and would accept the | operator instead, or whether you hate the whole operator concept regardless of how it is spelled. And to those who support this PEP, code examples where a dict merge operator will help are most welcome! ^1 Coming Real Soon Now™. -- Steven
