class(3) - Linux man page

Name

CLASS - Alias for __PACKAGE__

Synopsis

package Foo;
use CLASS;

print CLASS;                  # Foo
print "My class is $CLASS\n"; # My class is Foo

sub bar { 23 }

print CLASS->bar;     # 23
print $CLASS->bar;    # 23

Description

CLASS and $CLASS are both synonyms for __PACKAGE__. Easier to type.

$CLASS has the additional benefit of working in strings.

Notes

CLASS is a constant, not a subroutine call. $CLASS is a plain variable, it is not tied. There is no performance loss for using CLASS over __PACKAGE__ except the loading of the module. (Thanks Juerd)
