Links for Devel::SizeMe
0 has a length of 0 because it's interpreted in perl as a string, instead of as a number.
Reporting back as a function when you overide the function... don't try to examine it... when dealing with perl.
$a = "A"
++$a; # $a = "B"
perl6 has a more defined behaviour, and supports --$a, unlike perl 5.
perldoc Scala::Util does a looks_like_number EXPR to see if it looks like a number...

2 dimenstional games, cross platforms.
Will use open gl as a backend.
games seem to be #1. Drawing, video, audio.
vlc - one of the back ends is SDL. (Because it works everywhere...)
SDL bindings have snagated. However, they stagnated, and didn't follow the upstream sdl directly. ...
Recently, a new small push for sdl bindings.
makes the documentation easier ot use /
SDLX for perlish apis on top of SDL.
Trick - download codmpletely off of githb.
Then Alien SDL.
(Go out and fetch underlying for building external library and build it so it works.)
Build it from scratch from source. :-/
Then, seperately SDL_perl
then switch branches to redesign branch (OR JUST WAIT A FEW MONTHS)...
shooter.pl - frozen bubble to work. minor glitches.
Integrate Coro.
sdl_coro_repl
make_box(rand int rand 604 int rand 400) for 1..100
very cool demo, all in perl, in urser space.
Coro - copperative threads for perl, not pre-emptive...

Scala::Util , weaken
perl uses reference counting, because it works.
until you have
my $a;
$a = ['x',x1024 * 160, \$a];
weaken $a ->[1];

use DateTime;
my $agent = WWW::Mechanize->new( autocheck => 1,);

my $text = $agent->field('text');
my $now = DateTime->now->ymd;

$text = $status . "\n\n" . $text;
$agent->field('text', $text);
$agent->click('Save');
print "Content:\n" . $agent->content;
Notes from zaz:
1. Determine what you want to do
2. Use WWW::Mechanize::Shell
as a command line tool for doing what you need.
3. Eg. Shell> get
http://cpan.org
4. script out.pl
If you type "script out.pl" on the command shell, it will generate a script based upon what you did in WWW::Mechanize::Shell.
Then, edit that script as necessary.
Firebug (firefox plugin) ++ for examining html on web pages.
See also WWW::HtmlUnit, which is Brock's www library that supports javascript (which www-mechanize does not.)
Another alternative is lwp-simple, but that doesn't have form parsing / other features.
