in reply to Multi-line comments in perl code?

$comment = <<'EOC' This is a multiline comment. You can even indent it! Look And come back To the margin. EOC
Of course the word comment is used here in its widest sense.

    Such an assignment has to end somewhere (semicolon, block end, EOF) to be syntactically correct.

    For sake of simplicity, assuming it is really just a comment (as opposed to production data), right on the same line, as in

    $comment = <<'EOC'; bla bla EOC

    And while you are on it you can even give perl a hint that it can forget about that content as soon as possible:

    $comment = <<'EOC' if 0;

    Of course, whether you should resort to such "comments" is a completely different question.

    Your solution

    • is not strict-safe, but that can be fixed with a my
    • is not optimized away,
    • doesn't have indentable directives.

    The following doesn't suffer from those limitations:

    0 && q{ ... };
    0 && comment && q{ ... };
    use constant _comment_ => 0; _comment_ && q{ ... };
