+# The (future of the) Black code style
+
+```{warning}
+Changes to this document often aren't tied and don't relate to releases of
+_Black_. It's recommended that you read the latest version available.
+```
+
+## Using backslashes for with statements
+
+[Backslashes are bad and should be never be used](labels/why-no-backslashes) however
+there is one exception: `with` statements using multiple context managers. Before Python
+3.9 Python's grammar does not allow organizing parentheses around the series of context
+managers.
+
+We don't want formatting like:
+
+```py3
+with make_context_manager1() as cm1, make_context_manager2() as cm2, make_context_manager3() as cm3, make_context_manager4() as cm4:
+    ...  # nothing to split on - line too long
+```
+
+So _Black_ will eventually format it like this:
+
+```py3
+with \
+     make_context_manager(1) as cm1, \
+     make_context_manager(2) as cm2, \
+     make_context_manager(3) as cm3, \
+     make_context_manager(4) as cm4 \
+:
+    ...  # backslashes and an ugly stranded colon
+```
+
+Although when the target version is Python 3.9 or higher, _Black_ will use parentheses
+instead since they're allowed in Python 3.9 and higher.
+
+## Improved string processing
+
+Currently, _Black_ does not split long strings to fit the line length limit. Currently,
+there is [an experimental option](labels/experimental-string) to enable splitting
+strings. We plan to enable this option by default once it is fully stable. This is
+tracked in [this issue](https://github.com/psf/black/issues/2188).
