| Subject: | Suggested policy: redundant () in postfix control flow |
Because 'if', 'foreach' and so on require parentheses in their block
form, newcomers may write code like
say 'debug flag is on' if ($debug);
The extra () round the condition are not needed and not the usual
Perl style. There should be a policy to warn about them. It doesn't
matter if the policy doesn't catch 100% of cases as long as it warns
about the most common ones.
