Re^2: Dereferencing a Hash of Arrays

Hmm ... so why does this work?

my @idontgetit = values %alphabet;

say for @idontgetit->[0]->[0];

(It doesn't "work" in the sense of printing out what's desired but it does print out part of what's desired.)

`@idontgetit` holds the two array refs. `@idontgetit->[0]` indexes the first one of it, and the second `->[0]` indexes the first element of the (inner) array. BTW, `@idontgetit->[0]->[0]` should better be written as `$idontgetit[0]->[0]` (turn on warnings, and Perl will tell you why).	[reply] [d/l] [select]

I saw that warning before (I try to crack these nuts for a few hours before I ask the monks). I failed with `$idontgetit->[0]->[0]` and just went back to the `@` syntax since it printed anything. Sometimes Perl forgives my syntax, sometimes not.	[reply] [d/l] [select]
