=head1 DESCRIPTION |
16
|
|
|
|
|
|
|
|
17
|
|
|
|
|
|
|
A "cast" in PPI terms is one of more characters used as a prefix which force |
18
|
|
|
|
|
|
|
a value into a different class or context. |
19
|
|
|
|
|
|
|
|
20
|
|
|
|
|
|
|
This includes referencing, dereferencing, and a few other minor cases. |
21
|
|
|
|
|
|
|
|
22
|
|
|
|
|
|
|
For expressions such as C<@$foo> or C<@{ $foo{bar} }> the C<@> in both cases |
23
|
|
|
|
|
|
|
represents a cast. In this case, an array dereference. |
