## Description A method that read a class variable once reads it again after `remove_class_variable`. The second read does not raise NameError. It returns a broken value, and a use of that value causes a segmentation fault. ## Step...hasumikin (hitoshi hasumi)
PR: (WIP) ### What this adds This ticket adds the run-length methods of the String bit operation API. A run is a maximal sequence of consecutive bits with the same value. The methods build on the region arguments of #22279 and on t...hasumikin (hitoshi hasumi)
