       This policy is part of the "Perl::Critic::Pulp" add-on.  It reports POD verbatim paragraphs which contain
       markup like B<> or C<>.  That markup will appear literally in the formatted output where you may have
       meant fontification.

           =head1 SOME THING

           Paragraph of text introducing an example,

               # call the C<foo> function      # bad
               &foo();

       This is purely cosmetic so this policy is low severity and under the "cosmetic" theme (see "POLICY
       THEMES" in Perl::Critic).  Normally it means one of two things,

       •   You  want  markup  --  it should be a plain paragraph not a verbatim indented one.  An "=over" can be
           used for indentation if desired.

       •   You want verbatim -- replace the markup with an ascii approximation like "func()" or perhaps "*bold*"
           or "_underline_".

       Don't forget that a verbatim paragraph extends to the next blank line and includes unindented lines until
       then too (see "Pod Definitions" in perlpodspec).  If you forget the  blank  line  then  the  verbatimness
       continues

           =pod

               $some->sample;
               code();
           And this was I<meant> to be plain text.    # bad

   MarkupForms
       The  check  for markup is unsophisticated.  Any of the POD specified "I<" "C<" etc is taken to be markup,
       plus "J<" of "Pod::MultiLang".

           I<       # bad
           B<       # bad
           C<       # bad
           L<       # bad
           E<       # bad
           F<       # bad
           S<       # bad
           X<       # bad
           Z<       # bad
           J<       # bad, for Pod::MultiLang

       It's possible a "<" might be something mathematical like "X<Y", but in practice spaces "X < Y"  or  lower
       case letters are more common (and are ok).

       "DB<1>"  style sample Perl debugger output is exempted (see perldebug).  It's uncommon, but not likely to
       have intended "B<>" bold.

           DB<123> dump b        # ok

   Disabling
       If a verbatim paragraph is showing how  to  write  POD  markup  then  you  can  add  an  "=for"  to  tell
       "ProhibitVerbatimMarkup"  to  allow  it.   This  happens  most  often  in documentation for modules which
       themselves operate on POD markup.

           =for ProhibitVerbatimMarkup allow next

               blah blah E<gt> etc

           =for ProhibitVerbatimMarkup allow next 2

               Two verbatims of C<code>

               or B<bold> etc

       The usual no critic works too,

           ## no critic (ProhibitVerbatimMarkup)

       But the annotation must be before any "__END__" token, and if the POD is after an  "__END__"  token  then
       "Perl::Critic" 1.112 up is required.  An "=for" has the advantage of being together with the exception.

       As  always  if  you  don't  care at all about this at all then disable "ProhibitVerbatimMarkup" from your
       .perlcriticrc in the usual way (see "CONFIGURATION" in Perl::Critic),
