This makes sure that the method new from the class/package Class is called. This makes just a difference if in the caller package is a sub called Class. See e.g. `H:\>perl package Class; sub new { print "hello\n"; } package main; sub Class { print "not in Class\n"; } Class->new(); ^Z not in Class Can't call method "new" without a package or object reference at - lin +e 9. H:\>` [download] Here main::Class is called by accident... Best regards, perl -e "s>>F>e=>y)\martinF)stronat)=>print,print v8.8.8.32.11.32"	[reply] [d/l]

sub new {
  print "hello\n";
}
package main;
sub Class {

}
Class->new();
^Z
