%description
|
|
Aliasing is the phenomenon where two different expressions actually refer
|
|
to the same thing. Modifying one will modify the other, and if you take a
|
|
reference to both, the two values are the same.
|
|
|
|
Aliasing occurs in Perl for example in for-loops and sub-calls:
|
|
|
|
for $var ($x) {
|
|
# here $var is an alias to $x
|
|
}
|
|
|
|
foo($y);
|
|
sub foo {
|
|
# here $_[0] is an alias to $y
|
|
}
|
|
|
|
Data::Alias is a module that allows you to apply "aliasing semantics" to a
|
|
section of code, causing aliases to be made wherever Perl would normally
|
|
make copies instead. You can use this to improve efficiency and
|
|
readability, when compared to using references.
|
|
|
|
The exact details of aliasing semantics are below under DETAILS.
|
|
|
|
Perl 5.22 added some support for aliasing to the Perl core. It has a
|
|
different syntax, and a different set of operations, from that supplied by
|
|
this module; see perlref/Assigning to References. The core's aliasing
|
|
facilities are implemented more robustly than this module and are better
|
|
supported. If you can rely on having a sufficiently recent Perl version,
|
|
you should prefer to use the core facility rather than use this module. If
|
|
you are already using this module and are now using a sufficiently recent
|
|
Perl, you should attempt to migrate to the core facility.
