Improved attribute handler semantics for enhanced software performance.
The module's SYNOPSIS features various attribute handler subroutines such as Good, Bad, Ugly, Omni, AUTOATTR, PREATTR, and POSTATTR, each with its own unique functionality. The Good subroutine, for example, is invoked for any scalar variable with a :Good attribute, provided the variable was declared in MyClass or a derived class, or typed to MyClass. The subroutine can then be used to execute any desired action on $referent within the INIT phase.
AUTOATTR is particularly noteworthy since it is automagically invoked for any scalar, array, hash, or subroutine with an attribute for which no explicit handler is defined. This feature functions similarly to sub AUTOLOAD for method calls. Meanwhile, PREATTR and POSTATTR subroutines are automagically invoked before and after any other attribute handlers respectively.
Overall, Attribute::Handlers::Prospective provides a convenient and customizable solution for setting attribute handlers in Perl.
