Subject​: Dead link in perldoc.perl.org MRO documentation

This is a bug report for perl from freethunk@​fastmail.fm,
generated with the help of perlbug 1.40 running under perl 5.20.2.

---

On the page http​://perldoc.perl.org/mro.html, the link to the
original Dylan paper is dead.
original link​: http​://haahr.tempdomainname.com/dylan/linearization-oopsla96.html

a working link (from Wikipedia)​:
http​://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.19.3910&rep=rep1&type=pdf

(Maybe this should have been wishlist, but one of the best
things about Perl is how good its documentation. Keep up
the good work!)

Note that perl5-porters does not maintain the website perldoc.perl.org. So while this is changed in the repository, it will probably not appear at that website until its maintainer updates, probably after issuance of perl-5.28 in May.
