20 // We want to support properties, event sources and events sinks through
21 // explicit declarations, using templates and specialization to make the
22 // effort as painless as possible.
23 //
24 // This means we have the following domains :
25 //
26 // - Type Information for categorizing built in types as well as custom types
27 // this includes information about enums, their values and names
28 // - Type safe value storage : a kind of wxVariant, called right now wxxVariant
29 // which will be merged with wxVariant
30 // - Property Information and Property Accessors providing access to a class'
31 // values and exposed event delegates
32 // - Information about event handlers
33 // - extended Class Information for accessing all these
