I was looking for a way to use the here-document (<<DELIMITER;) to set some data section in the class.

But this sections need to be exactly as they where declared, soo, if some variable exists there can't be parsed.

Soo, this data:

$data = <<DATAFOO;
bla bla bla $globalvar
DATAFOO

print "$data\n" ;
[download]

prints:

bla bla bla
[download]

But I need that:

bla bla bla $globalvar
[download]

Looking at perldoc I found

## From perldiag:
=item Use of bare << to mean <<"" is deprecated

(D deprecated) You are now encouraged to use the explicitly
quoted form if you wish to use an empty line as the 
terminator of the here-document. 

## From perlop

    Customary  Generic        Meaning         Interpolates
    ''     q{}          Literal          no
    ""    qq{}          Literal          yes
    ``    qx{}          Command          yes*
        qw{}         Word list          no
    //     m{}       Pattern match      yes*
        qr{}          Pattern          yes*
         s{}{}        Substitution      yes*
        tr{}{}      Transliteration      no (but see below)
        <<EOF                 here-doc            yes*

    * unless the delimiter is ''.
[download]

Soo, testing some codes I saw that is possible to write that:

$data = <<'DATAFOO';
bla bla bla $globalvar
DATAFOO

print "$data\n" ;
[download]

And the output is:

bla bla bla $globalvar
[download]

OK, I found what I want. But the use of <<'DELIMITER'; is right/maintained? It works, but I never saw that and is not well documented, or I'm the only one that doesn't know that?

If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
