Params::Clean

I recently used Params::Clean, a Perl module designed to process @_ as positional, named, flag, list, and typed arguments. It's an easy-to-use piece of software that can help developers avoid starting their sub with my ($x, $y, $z) = @_; Instead, they can use Params::Clean's args function, which returns any combination of positional, named, and flagged arguments.

The SYNOPSIS demonstrates how to use args in various scenarios. Instead of getting positional arguments, named arguments, and flags, developers can simply include them in their args function call. Any of the three types of argument (positional, named, and flag) are optional, and order doesn't matter if they are repeatable. If no types are specified, integers are taken as positional arguments, and text is taken as named arguments.

Moreover, developers can retrieve any arguments left over after pulling out NAMES/FLAGS/POSNs/etc. Additionally, they can collect arguments that qualify as matching a certain type. For instance, developers can specify a list by giving starting and (optional) ending points, which includes an endpoint in the returned list.

Overall, Params::Clean is a useful Perl module for handling arguments in various ways. It offers a wide range of functions and makes the task of handling arguments much easier.
