[New-bugs-announce] [issue25137] Behavioral change / regression? with nested functools.partial

[Markus Holtermann]

New submission from Markus Holtermann:

Since #7830 nested partials are flattened. This is a behavioral change that causes a test failure in Django because we use nested partials to resolve relationships between models: https://github.com/django/django/pull/4423#issuecomment-138996095

In my opinion this is a regression since there's no way to turn off the new behavior.
