       UNIVERSAL::require - require() modules from a variable


         # This only needs to be said once in your program.
         require UNIVERSAL::require;

         # Same as "require Some::Module"
         my $module = 'Some::Module';
         $module->require or die $@;

         # Same as "use Some::Module"
         BEGIN { $module->use or die $@ }


       If you've ever had to do this...

           eval "require $module";

       to get around the bareword caveats on require(), this module is for you.  It creates a
       universal require() class method that will work with every Perl module and its secure.  So
       instead of doing some arcane eval() work, you can do this:


       It doesn't save you much typing, but it'll make a lot more sense to someone who's not a
       ninth level Perl acolyte.



         my $return_val = $module->require           or die $@;
         my $return_val = $module->require($version) or die $@;

       This works exactly like Perl's require, except without the bareword restriction, and it
       doesn't die.  Since require() is placed in the UNIVERSAL namespace, it will work on any
       module.  You just have to use UNIVERSAL::require somewhere in your code.

       Should the module require fail, or not be a high enough $version, it will simply return
       false and not die.  The error will be in $@ as well as $UNIVERSAL::require::ERROR.

           $module->require or die $@;


           my $require_return = $module->use           or die $@;
           my $require_return = $module->use(@imports) or die $@;

       Like "UNIVERSAL::require", this allows you to "use" a $module without having to eval to
       work around the bareword requirement.  It returns the same as require.

       Should either the require or the import fail it will return false.  The error will be in

       If possible, call this inside a BEGIN block to emulate a normal "use" as closely as

           BEGIN { $module->use }


       UNIVERSAL::require makes use of "eval STRING".  In previous versions of UNIVERSAL::require
       it was discovered that one could craft a class name which would result in code being
       executed.  This hole has been closed.  The only variables now exposed to "eval STRING" are
       the caller's package, filename and line which are not tainted.

       UNIVERSAL::require is taint clean.
