Bindings To-do:

• Add support for callbacks with non-void return types
• Add support for WebIDL namespaces
• Add support for generating name getters / setters / deleters
• Add support for generating index getters / setters with custom names
• Add support for maplike<> declarations
• Add support for setlike<> declarations
• Add support for Promise<> attributes
• Remove special casing of RegExp from overloading
• Add support for BufferType specialization in IDLTypes (currently implemented as IDLInterfaces)
• Stop invoking GetMethod(V, @@iterator) twice for sequence/FrozenArray disambiguation in overloading and union conversion
• Implement / verify FrozenArray reference semantics without [CachedAttribute]
• Add support for [SameObject]
• Add support for the remaining steps in the union conversion code
• Remove special casing of enums by passing context (attribute assignment, function parameter, dictionary assignment) to conversion functions
• Add better exception messages for all conversions
• Move all exception helpers out of JSDOMBindings.h and into its own header

Maybe:

• Split JSDOMConvert up into separate files per type
