Maybe something else has turned fatal warnings on globally, like Moo
used to do?

I don't know how else you would get the following fatal error, unless
something is actually dying with the message "Use of uninitialized
value in subroutine entry"

  Use of uninitialized value in subroutine entry at
  /home/hermann/perl5/perlbrew/perls/perl-5.26.2/lib/site_perl/5.26.2/HTTP/Server/Simple.pm
  line 397.
