my $var =

            [ # Here is the first element of the top anon array - it i
+s also an anon array
                {

            ], # end of 1st value of the top anon array

            {  # Here is the 2nd value of the top anon array - It's an
+ anon hash 
                'rm' => 'start',
                'dummy' => ''
            }
        ];
# So to access 'rm' you need the 2nd element of the top array (aka [1]
+)
# Deref that with $var->[1] 
# The 2nd element is an anon hash. That is where you need the hash key
+ 'rm' (aka {rm})
# Deref that with $var->[1]->{rm}
 
print $var->[1]->{rm};
#prints 'start'
