How do I enter a multi-line comment in Perl? [duplicate]

POD is the official way to do multi line comments in Perl,

  code and

• How can I comment out a large block
  of Perl code?

The quick-and-dirty way to comment out more than one line of Perl is
to surround those lines with Pod directives. You have to put these
directives at the beginning of the line and somewhere where Perl
expects a new statement (so not in the middle of statements like the #
comments). You end the comment with =cut, ending the Pod section:

=pod

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=cut

The quick-and-dirty method only works well when you don’t plan to
leave the commented code in the source. If a Pod parser comes along,
your multiline comment is going to show up in the Pod translation. A
better way hides it from Pod parsers as well.

The =begin directive can mark a section for a particular purpose. If
the Pod parser doesn’t want to handle it, it just ignores it. Label
the comments with comment. End the comment using =end with the
same label. You still need the =cut to go back to Perl code from the
Pod comment:

=begin comment

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=end comment

=cut
