Issue #20433 has been updated by mame (Yusuke Endoh). Status changed from Open to Closed Yes, I have merged it since @matz said at the dev meeting today that he still wants to try this change in the next preview release. So closing. However, it may be reverted if the impact of the incompatibility is too large. ---------------------------------------- Bug #20433: Hash.inspect for some hash returns syntax invalid representation https://bugs.ruby-lang.org/issues/20433#change-110055 * Author: tompng (tomoya ishida) * Status: Closed * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- For these hashes, Hash.inspect returns a syntax invalid representation: ~~~ruby { :a! => 1 } # {:a!=>1} { :a? => 1 } # {:a?=>1} { :* => 1 } # {:*=>1} { :== => 1 } # {:===>1} { :< => 1 } # {:<=>1} ~~~ `eval(hash.inspect)` will raise SyntaxError. Although inspect does not guarantee that the result can be eval-ed, it'd be confusing for these few cases. Maybe related to https://bugs.ruby-lang.org/issues/20235 -- https://bugs.ruby-lang.org/
