Can you give us a list of the compile-time "duck typing" protocols?

 Iterator<T> iterator ()        -> 'foreach'
 T? next_value ()               -> alternative 'foreach' iterator protocol

 T get (int index)              -> indexer access ('[index]')
 void set (int index, T item)

 bool contains (T needle)       -> 'in' operator

 T slice (long start, long end) -> slicing ('[start:end]')

 string to_string ()            -> string templates

Am I missing something?
