Update to 2.002002 (rhbz#2183727)
    
    - New upstream release 2.002002
      - Provide //= for default arguments, which are also used when the caller
        passes in undef
      - Provide more type combinators in parameter declarations: In addition to |
        (union types), now ~ & / are also supported (for
        complement types, intersection types, and alternative types, respectively)
      - Enable type coercions: if a parameter has a declared type and that type
        supports coercions ($type->has_coercion returns true), call its
        ->coerce($value) method to transform arguments before type checking
      - Enable inline type checks: if a parameter has a declared type and that
        type supports inlining ($type->can_be_inlined returns true), its inline
        code (as provided by ->inline_check('$value')) is baked into the function
        definition instead of a call to ->check($value), which may speed up type
        checks
      - Move a big chunk of tests to xt/ (author testing only)
      - Remove xt/ from the distribution
      - Enable parallel testing by default (with -j4)
      - Fix (hopefully) Windows builds using nmake.exe
      - Work around old versions of ExtUtils::MakeMaker not providing
        is_make_type(), whose version dependency is undocumented (sigh)
      - Restrict GNU syntax for exporting variables to type 'gmake'; should fix
        building on BSD, Solaris, etc.
      - Declare dependency on ExtUtils::MakeMaker 7+ and remove compatibility code
        for older versions
