There's more than one way to do things

( #3333=superdoc: print w/replies, xml ) Need Help??

I did try undef, but got warnings, so figured it was verboten. I ought to have continued with my experiments.

Here's something fun. Acme::Ref breaks on recent Perls, but it's a one line patch to fix it. (The _deref function needs to take a long argument instead of an int.)

use strict; use warnings; use feature 'say'; { package Local::Class; sub new { my ( $class ) = ( shift ); bless {}, $class; } sub AUTOLOAD { my ( $method ) = ( our $AUTOLOAD =~ /([^:]+)$/ ); if ( $method =~ /^(ARRAY|HASH|SCALAR|REF)/i ) { require Acme::Ref; my $real_coderef = $_[0]->can("HANDLE_$1") or die "Cannot handle $1 method"; splice @_, 1, 0, do { local $SIG{__WARN__} = sub {}; Acme: +:Ref::deref($method); }; goto $real_coderef; } return if $method eq 'DESTROY'; die "Could not load $method via AUTOLOAD"; } sub HANDLE_ARRAY { my ( $self, $array, @args ) = ( shift, shift, @_ ); say for @$array; } sub HANDLE_HASH { say "whatever"; } # etc... }; my $object = 'Local::Class'->new(); my $array = [ "Hello", "world" ]; $object->$array; $object->${\ [ "And", "again" ] };

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 or How to display code and escape characters are good places to start.
