Please no. The "cuteness" value of abusing the operator to indicate information flow got old shortly after C++ did it, and it doesn't help. With normal operator overloading, you can say "the + operator means addition", and then define "addition" for different types. Perhaps that ship has sailed, since we already have division between path objects, but at least in that example it is VERY closely related. There's no use of "<<" inside string literals with dictionaries the way there's "/foo/bar/spam" in paths. Dictionary merging is a form of addition. It's also related to set union, which is well known as part of the pipe operator. Either of those is far better than abusing left shift.
