%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 the /DETAILS
|
|
manpage.
