       A CPAN::Meta::Requirements::Range object models a set of version constraints like those specified in the
       META.yml or META.json files in CPAN distributions, and as defined by CPAN::Meta::Spec; It can be built up
       by adding more and more constraints, and it will reduce them to the simplest representation.

       Logically impossible constraints will be identified immediately by thrown exceptions.

with_string_requirement
         $req->with_string_requirement('>= 1.208, <= 2.206');
         $req->with_string_requirement(v1.208);

       This method parses the passed in string and adds the appropriate requirement.  A version can be a Perl
       "v-string".  It understands version ranges as described in the "Version Ranges" in CPAN::Meta::Spec. For
       example:

       1.3
       >= 1.3
       <= 1.3
       == 1.3
       != 1.3
       > 1.3
       < 1.3
       >= 1.3, != 1.5, <= 2.0
           A  version number without an operator is equivalent to specifying a minimum (">=").  Extra whitespace
           is allowed.

   with_range
        $range->with_range($other_range)

       This creates a new range object that is a merge two others.

   with_exact_version
         $range->with_exact_version( $version );

       This sets the version required to exactly the given  version.   No  other  version  would  be  considered
       acceptable.

       This method returns the version range object.

   with_minimum
         $range->with_minimum( $version );

       This  adds  a  new  minimum  version  requirement.   If  the new requirement is redundant to the existing
       specification, this has no effect.

       Minimum requirements are inclusive.  $version is required, along with any greater version number.

       This method returns the version range object.

   with_maximum
         $range->with_maximum( $version );

       This adds a new maximum version requirement.  If  the  new  requirement  is  redundant  to  the  existing
       specification, this has no effect.

       Maximum requirements are inclusive.  No version strictly greater than the given version is allowed.

       This method returns the version range object.

   with_exclusion
         $range->with_exclusion( $version );

       This adds a new excluded version.  For example, you might use these three method calls:

         $range->with_minimum( '1.00' );
         $range->with_maximum( '1.82' );

         $range->with_exclusion( '1.75' );

       Any version between 1.00 and 1.82 inclusive would be acceptable, except for 1.75.

       This method returns the requirements object.

   as_struct
         $range->as_struct( $module );

       This  returns  a  data structure containing the version requirements. This should not be used for version
       checks (see "accepts_module" instead).

   as_string
         $range->as_string;

       This returns a string containing the version requirements in the format  described  in  CPAN::Meta::Spec.
       This  should only be used for informational purposes such as error messages and should not be interpreted
       or used for comparison (see "accepts" instead).

   accepts
         my $bool = $range->accepts($version);

       Given a version, this method returns true if the version specification accepts the provided version.   In
       other words, given:

         '>= 1.00, < 2.00'

       We will accept 1.00 and 1.75 but not 0.50 or 2.00.

   is_simple
       This  method  returns  true  if and only if the range is an inclusive minimum -- that is, if their string
       expression is just the version number.

       CPAN::Meta::Requirements::Range - a set of version requirements for a CPAN dist

         use CPAN::Meta::Requirements::Range;

         my $range = CPAN::Meta::Requirements::Range->with_minimum(1);

         $range = $range->with_maximum('v2.2');

         my $stringified = $range->as_string;
