Yes, in my suggestion you need to escape false-newline-end-of-statement in
some few cases, like in Python.

What you written (which doesn't make any sense, I don't know what's the
point of putting shitty and unreal examples to prove a point) need a
escape at the end of the line, but this (more realistic) version doesn't:

auto a = b(
    c)

Because when you don't expect a statement to finish until the closing ) is
found (which is *exactly* the same behavior you get now, so please don't
bring the "meaningful errors" argument again =).

I have a Python project with 6482 LOC and I have just 39 lines with line
continuation. I think adding an extra character (\) to 0.6% of the lines is
pretty acceptable if you get rid of the extra character (;) at the end of
the line in the other 99.4% =)

Really. You are telling me that is ugly to have a '\' in 0.6% lines of code
but is pretty to have ';' in 100% of them??? It doesn't makes any sense to
me...

Is *that* hard to read the entire message? I said ';' is OPTIONAL (and
that's the key for backward compatibility). So you can perfectly write:

if (a == b) { ++i; ++j } else { --i; --j }

"Yuk."
