what about the original bug report? it's a documentation error or just
a magic feature?

1. It prints "AA" because PHP will convert an undefined constant to a
string. (and throws a warning "Notice: Use of undefined constant AA -
assumed 'AA'")
2. Constants are supposed to be scalar only.
No bug here Nuno.

Maybe there an engine error here. Take a look at this code:
<?
$tidy = new tidy;
define('aa', $tidy);
print_r(AA);
?>
outputs:
Warning: Constants may only evaluate to scalar values in
C:\cygwin\home\Nuno\constants.php on line 3

1) It seems that in fact this works, but outputs a couple of errors and
echoes the name of the constant, too. Need a fix in the engine.
2) constants are suposed to scalar data or they may have
objects/resources?

Description:
------------
http://www.php.net/manual/en/language.constants.php
"Only scalar data (boolean, integer, float and string) can be contained
in constants."
http://www.php.net/manual/en/function.mysql-connect.php
"resource mysql_connect ( ... )"
According to the documentation, "Expected result" is an E_NOTICE error
or something, but I guess the "Actual result" below implies that a
mysql link "resource" is actually an integer (4?). perhaps the
documentation in either of the two places listed above, or in the
define() man page, should reflect this fact?
Reproduce code:
---------------
$dbLink = mysql_connect($dbServerName, $dbUser, $dbPassword);
define('DB_LINK',$dbLink);
var_dump(DB_LINK);
echo gettype(DB_LINK);
Expected result:
----------------
see above.
Actual result:
--------------
resource(4) of type (mysql link)
resource
