Perl::Critic::Policy::Lax::ProhibitStringyEval::ExceptForRequire

NAME

Perl::Critic::Policy::Lax::ProhibitStringyEval::ExceptForRequire

VERSION

version 0.008

DESCRIPTION

Sure, everybody sane agrees that stringy "eval" is usually a bad thing, but sometimes you need it, and you don’t want to have to stick a "no critic" on the end, because dangit, what you are doing is just not wrong!

See, "require" is busted. You can’t pass it a variable containing the name of a module and have it look through @INC. That has lead to this common idiom:

  eval qq{ require $module } or die $@;

This policy acts just like BuiltinFunctions::ProhibitStringyEval, but makes an exception when the content of the string is PPI-parseable Perl that looks something like this:

  require $module
  require $module[2];
  use $module (); 1;
