I found this code example on Stack Overflow to prettyprint a hash:
(link:
http://stackoverflow.com/questions/2431032/how-to-print-a-key-value-using-the-perl-hases/2431139#2431139
)
use strict;
use warnings;
my %hash = (2009 => 9, 2010 => 10);
print join (" => ", each %hash), "\n" while <keys %hash>;
My question is: what is the angle bracket operator doing? I know its
use as <FILE>, <$file>, and <*.glob>, but I've never seen it used like
this, and I can't see anything in perlop#I/O Operators which would
help. This code works on perl 5.8.8 so it's been a feature for some
time, so it would surprise me if it's not documented anywhere, but I
just can't find it.
