42 ... in your application class:
43
44 package MyApp;
45
46 use MyApp::Validator;
47
48 thing ['a', 'b'];
49
50 ... in your application:
51
52 package main;
53
54 my $app = MyApp->new;

57 This module (while experimental) encapsulates the exporting of keywords
58 and routines. It applies the Validation::Class framework along with any
59 keyword routines and/or sub-routines specified with the apply_spec()
60 method. It does this by simply by copying the spec into the calling
61 class.
62
63 To simplify writing exporter modules, "Validation::Class::Exporter"
64 also imports "strict" and "warnings" into your exporter module, as well
65 as into modules that use it.

68 apply_spec
69 When you call this method, "Validation::Class::Exporter" builds a
70 custom "import" method on the calling class. The "import" method will
71 export the functions you specify, and can also automatically export
72 "Validation::Class" making the calling class a Validation::Class
73 derived class.
74
75 This method accepts the following parameters:
76
77 • routines => [ ... ]
78
79 This list of function names only will be exported into the
80 calling class exactly as is, the functions can be used
81 traditionally or as keywords so their parameter handling should
82 be configured accordingly.
83
84 • settings => [ ... ]
85
86 This list of key/value pair will be passed to the load method
87 imported from "Validation::Class::load" and will be applied on
88 the calling class.
89
90 This approach affords you some trickery in that you can utilize
91 the load method to apply the current class' configuration to
92 the calling class' configuration, etc.
