Issue #20294 has been updated by kddnewton (Kevin Newton). In addition, it appears that integers with different bases are not handled: ```ruby { 0xA => 1, 10 => 1 } { 0b1 => 1, 1 => 1 } { 0o1 => 1, 1 => 1 } ``` ---------------------------------------- Bug #20294: Parser no longer warns on some duplicated keys https://bugs.ruby-lang.org/issues/20294#change-106945 * Author: kddnewton (Kevin Newton) * Status: Open * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Previously, the parser would warn on all duplicated keys. Now some cases are not handled: ```ruby { 100.0 => 1, 1e2 => 1 } { 100.0 => 1, 1E2 => 1 } { 100.0 => 1, 100.00 => 1 } { 100.0r => 1, 100.00r => 1 } { 100.0i => 1, 100.00i => 1 } ``` -- https://bugs.ruby-lang.org/
