This Pull Request adds an error report when a dataclass field is declared as
Final, hasinit=False, and lacks a default value, as discussed in Issue#13119. This change adds a check to detect this combination while avoiding complex control flow analysis, as requested. It also flags no error if there's a__post_init__method, to avoid possible false positives.Test cases were adapted from PR#14285. I also added a new test case for default values provided on the field declaration.
Thanks to@jakezych for the original test cases.
Fixes#13119
