Issue #20087 has been updated by jeremyevans0 (Jeremy Evans). Status changed from Open to Closed Fixed by commit:c452fe17ac679b4171c7de4f4004d61790828ba8 ---------------------------------------- Bug #20087: Uninitialized instance variable warning - obsolete documentation https://bugs.ruby-lang.org/issues/20087#change-105930 * Author: semaperepelitsa (Simon Perepelitsa) * Status: Closed * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- This warning got removed from Ruby 3.0: https://bugs.ruby-lang.org/issues/17055 But the documentation (ruby/doc/syntax/assignment.rdoc@master) still says:
An uninitialized instance variable has a value of +nil+. If you run Ruby with warnings enabled, you will get a warning when accessing an uninitialized instance variable.
