Tie is only one kind of magic. Magic scalars are actually quite common.

$1
$|
$ENV{PATH}
$ISA[0]
$tied{$k}
$tied[$i]
$#a
pos
substr
[download]

(Some of these only return magical scalars in lvalue context.)

Every tied hash and array uses them in order to call STORE on the hash or array when assigning to the scalar returned by $tied{$i} and $tied[$i].
