[Python-ideas] allow line break at operators

[Yingjie Lan]

Yeah, that might be a challenge for the Python interpreter, for it has to check if the next line is indented or not. But it might be worthwhile to take this trouble, so that the coder has more freedom, and the code is hopefully better to read.

I guess the issue here is that you can't tell if an expression is
complete without checking the indent of the following line. This is
likely not desirable.
