+- On `ErratumPushItem`, the `from_` attribute is now available under the preferred

+"""Helpers to deal with "from" vs "from_" issue in ErratumPushItem.
+
+The advisory model has a "from" field, which unfortunately clashes with
+a Python keyword of the same name. This prevents directly declaring the
+field as "from".
+
+Despite the clash, it is desirable to have the attrs field named "from"
+so that usage of this model does not have to be frequently accompanied
+by some "from_" => "from" renaming (e.g. before uploading to Pulp).
+
+It is possible to make this work by:
+
+- in the ErratumPushItem class, declare the attribute as "from_"
+- then, after the class is created, patch it to effectively rename it
+  to "from"
+
+This makes use of the __attrs_attrs__ attribute which is associated
+with each attrs class. Though the name implies it is private, this is
+a supported & documented method of extending the behavior of attrs,
+see: https://www.attrs.org/en/stable/extending.html
+
+A simpler trick may come to mind: just setattr(ErratumPushItem, 'from', attr.ib(...))
+to work around the inability to write "from = attr.ib(...)".
+Unfortunately, that does not work because the attrs library internally
+tries to eval some code of the form "<attr_name> = ...", which will never
+work if the name is a keyword.
