Seems to be a popular question for newcomers to ask how to access some component of a complicated structures.
The answer is to user the built-in debugger.
tlegrady@rw-q318:~$ perl -d t.pl
Loading DB routines from perl5db.pl version 1.3
Editor support available.
Enter h or `h h' for help, or `man perldebug' for more help.
main::(t.pl:5): my $data = [
DB<1> n
main::(t.pl:16): my $test = $data->{ name };
DB<1> x $data
0 ARRAY(0x70b910)
0 HASH(0x70b970)
'name' => 'Mary'
DB<2> x $data->[0]
0 HASH(0x70b970)
'name' => 'Mary'
DB<3> x $data->[0]{name}
0 'Mary'
When the debugger starts, it shows that it's about to execute line 5. I do a "next" ( 'n') to complete that, and then it's going to execute line 16. I query the debugger to show the value of $data, and then of its components. Since you're looking right at it, it's easy to tell you want array element '0', hash tag 'name'.
