in reply to [meta::cpan] Dependency vs Reverse Dependency

Ref::Util is an optional prereq for Specio, see Optional Prereqs.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    So is an "Optional Prereq" a "Reverse Dependency"?


    I mean by definition not by implementation of Metacpan.

      Possibly. For example, some modules may require a JSON parser but be agnostic about which JSON parser. You could install such a module without JSON::XS or without JSON::PP or without JSON::Foo but not without at least one of them. Individually they are not required but collectively at least one of them is. I'm not sure that the existing meta spec handles such a scenario in a logical, intuitive, consistent manner.


      I don't know the definiton, but the implementation seems to be here.
      map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
