This is what the meta object is for:
#!/usr/bin/perl
{ package Foo;
use Moose;
use warnings;
has num => ( is => "rw", isa => "Int" );
has str => ( is => "rw", isa => "Str" );
}
use strict;
use feature "say";
use warnings;
my $foo = Foo->new;
for my $attr ("num", "str") {
say "$attr is of type: ",
$foo->meta->get_attribute($attr)->type_constraint->name;
}
