Bug #17124
Updated by sawa (Tsuyoshi Sawada) over 3 years ago
```sh $ ruby -v -e "x='a'; x.match? /[a-z]/" ruby 2.8.0dev (2020-07-30T14:07:06Z master 352895b751) [x86_64-darwin18] -e:1: warning: ambiguous first argument; put parentheses or a space even after `/' operator ``` There is no `/` `/' operator in there and there is also no ambiguity as adding a space after the first `/` is a syntax error. Is it possible to remove the warning altogether when the argument is lexed as a regexp? The message could use a rewording too, maybe "ambiguous first argument; put parentheses around argument or add a space after `/' operator"
