Perl keywords are highlighted in a here-doc

Information

• Language: Perl
• Plugins: "Perl"

Description

This example is from Wikipedia https://en.wikipedia.org/wiki/Here_document#Perl :

my $sender = "Buffy the Vampire Slayer";
my $recipient = "Spike";

print <<"END";

Dear $recipient,

I wish you to leave Sunnydale and never return.

Not Quite Love,
$sender

END

PrismJS highlights and and return as if the body is parsed as Perl code:

The Wiki highlighting is closer to expectations:

Both are still somewhat incorrect, but the wiki style is spiritually closer than PrismJS

Code snippet

Test page

my $sender = "Buffy the Vampire Slayer";
my $recipient = "Spike";

print <<"END";

Dear $recipient,

I wish you to leave Sunnydale and never return.

Not Quite Love,
$sender

END

Start with the Perl plugin and the linked PrismJS test page, using the provided here-document example to reproduce the highlighting. Add regression coverage for the example and adjust the grammar so the here-document body is not parsed as Perl code; done means keywords such as "and" and "return" are no longer highlighted there.
