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)
