The Perl 5 module autobox provides an autobox pragma. It allows
|
||
|
|
methods to be called on integers, floats, strings, arrays, hashes,
|
||
|
|
and code references in exactly the same manner as blessed references.
|
||
|
|
The autoboxing is transparent: boxed values are not blessed into
|
||
|
|
their (user-defined) implementation class (unless the method elects
|
||
|
|
to bestow such a blessing) - they simply use its methods as though
|
||
|
|
they are.
|
||
|
|
The classes (packages) into which the native types are boxed are
|
||
|
|
fully configurable. By default, a method invoked on a non-object
|
||
|
|
is assumed to be defined in a class whose name corresponds to the
|
||
|
|
ref() type of that value - or SCALAR if the value is a non-reference.
|
||
|
|
This mapping can be overriden by passing key/value pairs to the use
|
||
|
|
autobox statement, in which the keys represent native types, and
|
||
|
|
the values their associated classes.
