What are good alternatives to type constraints, and how do they compare?

Keywords: Perl, type constraints, input validation, data integrity, Moose, MooseX::Types, Type::Tiny
Description: Explore effective alternatives to type constraints in Perl programming for ensuring data integrity and improving input validation.
# Example of using MooseX::Types for type constraints in Perl package MyApp::Types; use MooseX::Types -declare => [qw(PositiveInt)]; use MooseX::Types::Moose qw(Int); use overload '""' => sub { $_[0]->value }; subtype PositiveInt, as Int, where { $_ > 0 }; package MyApp::Example; use Moose; use MyApp::Types qw(PositiveInt); has 'age' => ( is => 'rw', isa => PositiveInt, required => 1, ); sub display_age { my $self = shift; return "Your age is: " . $self->age; } # Usage my $person = MyApp::Example->new(age => 25); print $person->display_age();
