NAME

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

DESCRIPTION

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

=head1 SEE ALSO

L<Foo::Bar>

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. But this is fairly minor matter, so this policy is under the cosmetic theme (see "POLICY THEMES" in Perl::Critic) and low priority.

A module can certainly appear more than once in a SEE ALSO, but L<> link just once and anything else 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/alarm>,
L<perlfunc/kill>     # ok

Disabling

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),
