This:

for (tie @ary, "My::Class", "some", "contents";) { ... }

is exactly what you should NOT be doing

Read: Tying-Arrays: If someone outside the class tries to dereference the object returned (doubtless thinking it an ARRAY ref), they'll blow up. This just goes to show you that you should respect an object's privacy.

FETCH and FETCHSIZE are exactly for that you can: 'respect an object's privacy':

Something like this:

my $aryt = tie @ary, "My::Class", "some", "contents"; @ary = ... ; for (0..($aryt->FETCHSIZE-1)) { do-something($aryt->FETCH($_)); }
