Another thing is the Haxe standard library, which guarantees certain features across all targets, including features that aren't normally available (like, say, Reflection in C++, if I understand correctly). If the feature is natively available, it falls through to the native implementation, if not, on that target the standard library provides enough code to enable the feature.
