Re: What does $::var means

It's basically just a shortcut for the package variable $main::var as demonstrated by:

package Foo;
use strict;
$::foo = "yayayaya";
                                                                      
+          
print $main::foo;

In your example the unqualified$var might be a different variable if it a lexical variable.

They are not the same variable. The lexical variable declared as `my $var` is only accessible within the scope within which it is defined, whereas the package variable `$main::var` is essentially accessible anywhere. The package variable appears in the global symbol table whereas the lexical variables have their own 'pad' so they occupy a different namespace. /J\	[reply] [d/l] [select]

For the difference between `$var` and `$::var` see the following code: `package Foo; $var = "hello\n"; $::var = "bye\n"; print $var; # hello print $Foo::var; # hello print $::var; # bye print $main::var; # bye package main; print $var; # bye !! print $Foo::var; # hello print $::var; # bye print $main::var; # bye` [download] So - as mentioned elsewhere - `$::var` is equivalent to `$main::var` while `$var` refers to the `$var` variable in the current package. -- Hofmator	[reply] [d/l] [select]
