But in the case where two major languages already agree on a syntax looking very like the one we're adopting here, I'd say that a more important concern is to avoid being confusingly similar-but-incompatible.

But in the case of Python, there is also a new string prefix. I don't know about other languages. Anyhoo, as long as we're convinced we won't eventually be doubling a third and fourth character (incompatibly), then I suppose it's okay. I like the extensible solution of a quoting character.
