The :: in perl

[be12dune09a]

I read the perltoot but I diden't understand what :: does in for exemple $Person::Something What is Something? A static member of the class Person or a variable that is particular for each object and can be used directly without any method call.

It's known as a package variable in Perl. It's pretty much the same as what a static variable does in Java.

ok than if I use a variable without my it also the same as a static variable in Java?

It's good practice to enable strict checking, which forces you to declare variables with `my' or `our', unless you're using the $Person::Something syntax for package variables you've mentioned above.

If you're not using strict, then yes: using a variable without pre-declaring what scope you want it to have will result in a package variable being created.
