Perl nested structures -

I have a question about complex structures in Perl

  My $ data1 = [ + {ID = & gt; 1, name = & gt; 'A'}, + {id = & gt; 2, name = & gt; 'B'}, + {id = & gt; 3, name = & gt; 'C' }, ]; My $ data3 = + {1 = & gt; + {ID = & gt; 1, name = & gt; 'A'}, 2 = & gt; + {ID = & gt; 2, name = & gt; 'B'}, 3 = & gt; + {ID = & gt; 3, name = & gt; 'C' }, };   
 How should I print "B"? What kind of data structure is that?  
 Thank you in advance   
 
 
 Try doing this:  
  print $ data1-> [1] - & gt; {Name}; # ARRAY ref print $ data3- & gt; {2} - & gt; {Name}; #hash referee   
 This will be a perl ARRAY and HASH Ref from  de-reference .  
  - & gt;   D-context  This is explicitly required only for the first "floor", ex:  
  print $ data1-> [1] { Name}; Print $ data3- & gt; {2} {name};   
 Also there are 2 more options that works. Like Chris Charlie, take a look at  
 
 to help you understand how your scalar ref looks, use, eg:  
  Print dumper $ data1; Print dumper $ data3;   
 should output:  
  $ VAR1 = [{'name' = & gt; 'A', 'id' = & gt; 1}, {'name' = & gt; 'B', 'ID' = & gt; 2}, {'name' = & gt; 'C', 'ID' = & gt; 3}]; $ VAR1 = {'1' = & gt; {'Name' = & gt; 'A', 'id' = & gt; 1}, '3' = & gt; {'Name' = & gt; 'C', 'ID' = & gt; 3}, '2' = & gt; {'Name' = & gt; 'B', 'ID' = & gt; 2}};   
 
  + {} , gives a good response to the syntax:  
 
 Disables where those places suspend a Anonymous hash should be a code block instead of context, but one rarely needs it. I'm guessing that the code has a wrong desire to be clear and consistent with those places, where it is unclear.
