$byname{Owen}{PHONE} is fine. use strict yould NOT complain.
I can't find the sentence that says $HoH{x}{y} means exactly the same
as $HoH{x}->{y}, but it does. And the perlxxx manpages are full of
examples.
Also try to run
perl -MO=Deparse -e "$HoH{x}{y} = 5;$HoH{x}->{y} = 6;"
You'll get
$HoH{'x'}{'y'} = 5;
$HoH{'x'}{'y'} = 6;
-e syntax OK
If you want to use strict:
perl -MO=Deparse -e "use strict; my %HoH; $HoH{x}{y} = 5;$HoH{x}-
>{y} = 6;"
