$delete Statement - Delete Objects

This section describes the $delete statement for deleting objects.

The $delete statement is for deleting objects using the following syntax:

$delete object_reference;

Examples of $delete statements:

# an empty class
$class dummy: {};

# create a "dummy" object
d = dummy();

# delete the "dummy" object
# d is assigned to $null after
$delete d;

# create a "dummy" object, then delete it.
$delete dummy();
