Programming Ruby 3.2 (5th Edition): B2.0 page 455, Table 13—Ruby operators


page 455, compared with The Ruby Programming Language by David Flanagan & Yukihiro Matsumoto, O’Reilly 2008, there is some discrepancy at the beginning of the table. And defined? is added.

Good question, I just inherited this table, but it doesn’t match the official reference at… precedence - Documentation for Ruby 3.3 – I’ll adjust it.
