Perl::Critic::Policy::ValuesAndExpressions::RequireInterpolationOfMetachars - Warns that you might have used single quotes when you really wanted double-quotes.
This Policy is part of the core Perl::Critic distribution.
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.
This Policy is not configurable except for the standard options.
Perl's own warnings pragma also warns you about this.
