[MacPerl] Dereferencing

[Peta Adams - John Murray <jmnc@lis.net.au>]

Charles,

I struggled with references for a while. Take:

$ref->xxx

A helpful focus for me was to regard the "->" bit to mean "Out of all that
$ref on the left refers to, just give me the bit that xxx on the right
signifies". Kind of like aiming an arrow "->" at part of a target.

While using $,@ or %, as in $$somescalarref or %$somehashref, gave me the
whole lot.

Maybe this is a little basic for where your at. If so no offence intended.
BTW ... enjoyed your tutorial.

Cheers ... John
