Well, it can, but then you would have to include the same amount of spaces in the quoted string:

print << '        END';
Text goes here...
        END

And to have the actual text indented, you'd have to so some search/replace:

my $text;
($text = <<'    END') =~ s/^\s+//gm;
        Indented text
    END
