Transitional syntax has the any type. As part of the transitional specification (which I hope to have ready soon), "any" is basically an untyped opaque cell with implicit coercion to/from primitive types and enums.

The problem is that "any" is not well-typed in C++. As long as its surface area is restricted to natives, gradually porting everything in the future should be doable. Baking it into the C++ API makes things difficult down the road though.
