Bug #16092: [doc] precedence of modifier-rescue
https://bugs.ruby-lang.org/issues/16092

----------------------------------------
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.
