Line continuation and comments

[Robert Latest]

I found myself building a complicated logical condition with many ands and ors
which I made more manageable by putting the various terms on individual lines
and breaking them with the "\" line continuation character. In this context it
would have been nice to be able to add comments to lines terms which of course
isn't possible because the backslash must be the last character on the line.

Question: If the Python syntax were changed to allow comments after line-ending
backslashes, would it break any existing code? I can't think of an example.
