From: daniel@...42.com Date: 2019-08-09T14:18:36+00:00 Subject: [ruby-core:94221] [Ruby master Bug#16092] [doc] precedence of modifier-rescue Issue #16092 has been reported by Dan0042 (Daniel DeLorme). ---------------------------------------- Bug #16092: [doc] precedence of modifier-rescue https://bugs.ruby-lang.org/issues/16092 * Author: Dan0042 (Daniel DeLorme) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- The docs state that modifier-rescue has lower precedence than assignments which have lower precedence than modifier-if. This is true for `v = expr rescue $! if condition` but not for `v = expr if condition rescue $!` which is treated as `(v = expr if condition) rescue $!` rather than `v = expr if (condition rescue $!)` This goes similarly for `defined? expr rescue $!` `not expr rescue $!` `expr1 and expr2 rescue $!` `expr1 or expr2 rescue $!` So maybe the documentation should state that modifier-rescue has **equal** precedence to modifier-if & others, with an **exception** made for assignments? I'm not entirely sure how to describe that exception though. -- https://bugs.ruby-lang.org/ Unsubscribe:
