I am using the example from 'Programming Perl (third edition)' Section 9.4.3
I guess my ultimate question would be, what have they been deprecated to?
You don't need to know, because they don't work at all in 5.10, and
besides, that example doesn't use them; you translated it incorrectly.
And an example would be GREATLY appreciated.
Somehow you got an arrayref containing a hashref inside $config{server},
and that maketh a pseudohash (see section 8.3.5):
my $sudoh = [ {foo => 1, bar => 2} ];
my %config = (server => $sudoh );
You wanted just the hashref there.
