Comment at: llvm/include/llvm/ADT/STLExtras.h:310-312
+/// A base type of mapped iterator, that is useful for building derived
+/// iterators that do not need/want to store the map function (as in
+/// mapped_iterator). These iterators must simply provide a `mapElement` method
----------------
Could this be implemented in mapped_iterator as an empty optimization if the mapping function happens to be stateless?
