no they are not the same:
#!/usr/bin/perl -w
use strict;
@_ = (1..5);
sub get_number{
print "@_\n";
}
print "&get_number:\t"; &get_number;
print "&get_number():\t"; &get_number();
print "get_number:\t"; get_number;
print "get_number():\t"; get_number();
__END__
print:
&get_number: 1 2 3 4 5
&get_number():
get_number:
get_number():
the first call really pass @_ implicitly to the function while the others do
not. one more reason why the '&' calling convention shouldn't be used.
