See reply to Glenn. Can you give an example of a dotted name that is
not a constant value pattern? An example of a non-dotted name that is?
If you can't do either (and I cannot)), then that's simply what "if
case long.chain.of.attributes:
That's a dotted name and so is a constant value pattern - read the PEP.
Every dotted name in a pattern is looked up using normal Python
name resolution rules, and the value is used for comparison by
equality with the matching expression (same as for literals).
Then I am surprised, which is worse. "long.chain.of.attributes" looks
like an assignment target, and I would have expected the case to have
been a name pattern.
