       This module gathers a list of recommended modules and versions and provides means to check if they are
       available.  It is a thin veneer around Module::Runtime.

       There are two major benefits over using Module::Runtime directly:

       •   Self-documents  recommended  modules  together  with  versions  at  the top of your code, while still
           loading them on demand elsewhere.

       •   Dies if a recommended module exists but fails to compile, but doesn't die if the module is missing or
           the version is insufficient.   This  is  not  something  that  Module::Runtime  offers  in  a  single
           subroutine.

         git clone https://github.com/dagolden/recommended.git

           use recommended 'Foo::Bar', {
               'Bar::Baz' => '1.23',
               'Wibble'   => '0.14',
           };

           if ( recommended->has( 'Foo::Bar' ) ) {
               # do something with Foo::Bar
           }

           # default version required
           if ( recommended->has( 'Wibble' ) ) {
               # do something with Wibble if >= version 0.14
           }

           # custom version required
           if ( recommended->has( 'Wibble', '0.10' ) ) {
               # do something with Wibble if >= version 0.10
           }

import
           use recommended 'Foo::Bar', {
               'Bar::Baz' => '1.23',
               'Wibble'   => '0.14',
           };

       Scalar  import  arguments  are  treated  as  module  names with a minimum required version of zero.  Hash
       references are treated as module/minimum-version  pairs.   If  you  repeat,  the  later  minimum  version
       overwrites the earlier one.

       The list of modules and versions are kept separate for each calling package.

   has
           recommended->has( $module );
           recommended->has( $module, $alt_minimum_version );

       The  "has"  method  takes  a module name and optional alternative minimum version requirement and returns
       true if the following conditions are met:

       •   the module was recommended in the current package (via "use recommended")

       •   the module can be loaded

       •   the module meets the default or alternate minimum version

       Otherwise, it returns false.  If the module exists but fails to compile, an error is thrown.  This avoids
       some edge-cases where things are left in an incomplete state or subsequent normal loads of the module  by
       other packages get a misleading error.

       The  module  is  loaded  without  invoking the module's "import" method, as running import on an optional
       module at runtime is just weird.
