We still have to read it after Black munges it.
Like Paul said, add parentheses -- it works for method chaining, string
I have written tens of thousands of lines of Pandas code, and I've taught
thousands of people to use Pandas. I've worked with the core developers of
Pandas as well.
This is the first time I've ever seen `\` line continuation used for fluent

This argument pretty much kills the proposal.

To my mind there are too many differences between running code as a
script and running it in the REPL. This would, presumably, add another
one: the initial line would be executed without waiting to see if there
is a dot continuation line. And it just feels wrong to have a complete

... and if you try that out, what you'll find is that black adds parentheses:
y = (
x.rstrip("\n")
Can we skip ahead to considering how to implement this? I can think of two
approaches: either hack the lexer to special-case a newline followed by a
period (which currently can never start a line), or redesign the syntax to
allow NEWLINE INDENT ‘.’ . NEWLINE ‘.’ DEDENT at the
