  # NAME
  
  Attribute::Predicate - add "is predicate" trait to Attributes
  
  # SYNOPSIS
  
  ```
  use Attribute::Predicate;
  
  class Foo {
      has $.bar is predicate;         # adds method "has-bar"
      has $.baz is predicate<bazzy>;  # adds method "bazzy"
  }
  
  Foo.new(bar => 42).has-bar;    # True
  Foo.new(bar => 42).bazzy;      # False
  
  ```
  
  # DESCRIPTION
  
  This module adds a `is predicate` trait to `Attributes`. It is similar in function to the "predicate" option of Perl's `Moo` and `Moose` object systems.
  
  If specified without any additional information, it will create a method with the name "has-{attribute.name}". If a specific string is specified, then it will create the method with that given name.
  
  The method in question will return a `Bool` indicating whether the attribute has a defined value.
