Historically, and also in Python, the backslash escapes the immediately
following character. That means that _nothing_ may follow the backslash and
that the backslash is not a "line continuation backslash" per se.

Now, there are ways around this, just add parens:

  if (a > 0
      and b > 0):

Note that this also applies to (), [] and {} when forming tuples, lists and
dicts, which you can spread across different lines.

I'd actually argue that even the currently used backslash is a bad idea to
have.
