I still think about these two kinds of concatenation in different ways, though. When I use implicit concatenation, I don't think in terms of taking two strings and joining them together. I'm just writing a single string literal that happens to span two source lines.
I believe that distinguishing them visually helps readability. Using + for both makes things look more complicated than they really are.
Thinking more about this, yes I see that "+" is really different for various reasons, when you just want to write a long string. "+" involves precedence rules, which is actually too much. Writing continuation lines with '\' is much less convenient, because you cannot insert comments. What I still don't like is the pure absence of anything that makes the concatenation more visible. So I'm searching for different ways to denote concatenating of subsequent strings. Or to put it the other way round: We also can see it as ways to denote the _interruption_ of a string. Thinking out loud... A string is built, then we break its construction into pieces that are glued together by the parser. Hmm, this sounds again more like triple-quoted strings.
