The Perl garbage collector uses simple reference counting during the normal
|
||
|
|
execution of a program. This means that cycles or unweakened references in
|
||
|
|
other parts of code can keep an object around for longer than intended. To
|
||
|
|
help avoid this problem, the reference count of a new object from its class
|
||
|
|
constructor ought to be 1. This way, the caller can know the object will be
|
||
|
|
properly DESTROYed when it drops all of its references to it.
