Perl::Critic::Policy::Documentation::ProhibitDuplicateSeeAlso - don't duplicate L<> links in SEE ALSO


This policy is part of the Perl::Critic::Pulp add-on. It asks you not to duplicate L<Foo> links in a SEE ALSO section.

    =head1 SEE ALSO


    L<Foo::Bar>    # bad

The idea is that for readability a given cross-reference should be linked just once and a duplicate is likely a leftover from too much cut-and-paste etc. This is minor matter so this policy is low severity and under the cosmetic theme (see "POLICY THEMES" in Perl::Critic).

A module can appear more than once in a SEE ALSO, but only L<> linked once. Anything else should be C<> markup or plain text.

    L<Foo::One>, L<Foo::Two>
    (C<Foo::Two> runs faster)     # ok

Links to different parts of a target POD are allowed,

    L<perlfunc/kill>     # ok


If you don't care about this then you can always disable ProhibitDuplicateSeeAlso from your .perlcriticrc file in the usual way (see "CONFIGURATION" in Perl::Critic),
