Trying to get facilty with hash arrays and I am having a nasty time. Please see the snippet below, Btw, I'm working out of A.L. Johnson's "Elements of Programming with Perl" pp.146. Could a you beakdown/explain the code, I'll tell you specifically where I'm stuck after the snippet:

students.dat ------------ Bill Jones : 2 : 35 Anne Smith : 3 : 41 $students {$fields[0]}->[$fields[1]]=$fields[2]

So looks like, $student is an anonyous hash reference. $fields[0] is the key (ie. key is student name). Taken in total the left side of the arrow is an anonymous array reference. It's the right side of the arrow I don't understand, what's the "=" doing.....Heck, I don't understand. Could a monk gently break it down for me? Help appreciated.
