In Perl it is an infix dereference operator. The if the rhs is an array subscript, or a hash key, or a subroutine, then the lhs must be a reference, can also be used as method invocation: invocant->method

Uses of  "->" Operator:
###################

1) Reference the method of a module.

use CGI;
my $cgi = new CGI ();
$cgi->header();

2) In Perl it is an infix dereference operator.

$arr = [ qw/ prabhath vamsi eswar sandhya God/];  #This is an Array Reference
print "n",$arr->[0];  #Right
print "n",$arr[0];     #Wrong as $arr is an array reference not an array      

@arr = qw/ prabhath vamsi eswar sandhya  God/;   #This is an Array
print "n",$arr->[0];  #Wrong
print "n",$arr[0];     #Right as @arr is an array
