re "allows one to use references as hash keys", I didn't realise this was a problem so to be certain I tried this:
#!/usr/bin/perl use Data::Dumper; my $var = "VARVALUE"; my @arr = ( 'ARRVAL1', 'ARRVAL2' ); my %hash = ( hashkey1 => hashval1, hashkey2 => hashval2 ); open my $fh, "| more"; my %HOfR = ( \$var => "valForRefOfVar", \@arr => "valForRefOfArr", \%hash => "valForRefOfHash", \&Sub => "valForRefOfSub", $fh => "valForRefOfGlob" ); print Dumper( \%HOfR ); sub Sub { }; produced the expected kind of results, i.e.:
$VAR1 = { 'ARRAY(0x2ddf0)' => 'valForRefOfArr', 'SCALAR(0x2ddd8)' => 'valForRefOfVar', 'GLOB(0x228b4)' => 'valForRefOfGlob', 'HASH(0x2ddcc)' => 'valForRefOfHash', 'CODE(0x456cc)' => 'valForRefOfSub' };
which makes me wonder what the original problem actually is.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
