Perl::Critic::Policy::ValuesAndExpressions::RequireInterpolationOfMetachars(3)

NAME
Perl::Critic::Policy::ValuesAndExpressions::RequireInterpolationOfMetachars - Warns that you might have used single quotes when you really wanted double-quotes.

AFFILIATION
This Policy is part of the core Perl::Critic distribution.

DESCRIPTION
This policy warns you if you use single-quotes or "q//" with a string that has unescaped metacharacters that may need interpolation. Its hard to know for sure if a string really should be interpolated without looking into the symbol table. This policy just makes an educated guess by looking for metacharacters and sigils which usually indicate that the string should be interpolated.

CONFIGURATION
This Policy is not configurable except for the standard options.

NOTES
Perl's own "warnings" pragma also warns you about this.
