ct: RE: hash of hash of array slices
This worked fine. However I was under the impression that any time you
worked with a slice that you had to surround the array in parenthesis.
When else does this not apply?

It should be:
foreach ( @{ $hash{$key1}{$key2} }[1 .. 10] ) { ... }
based on your other email.

This works
Foreach ( @{$hash{$key1}{$key2}} )
This does note
Foreach ( @{($hash{$key1}{$key2})[9..1]} )
This gives me this error
Can't use undefined value as an array reference.
