Here is what C has that Perl doesn't:
&
The address-of operator. Perl's
operator (for taking a reference) fills the
same ecological niche, however:
$ref_to_var = $var;
*
The dereference-address operator. Since Perl
doesn't have addresses, it doesn't need to dereference
addresses. It does have references though, so Perl's variable
prefix characters serve as dereference operators, and indicate
type as well: $
, @
,
%
, and &
. Oddly
enough, there actually is a *
dereference
operator, but since *
is the funny character
indicating a typeglob, you wouldn't use it the same way.
(TYPE)
The typecasting operator. Nobody likes to be typecast anyway.
