Ignoring the fact that I think Erica’s proposal is an improvement over the current state, a more general solution would be something like user-defined literals in C++11 (with whatever syntax). A playground could then pre-import the definitions of any literal types it wants to support, without having to change the language / compiler any time a new literal type is added.

I’m not sure whether this use-case is so important (or I’m overlooking something basic) that these items need such special treatment (e.g. #-prefix); couldn’t one just offer global factory functions for the literals in question and treat them specifically in Xcode’s playground UI?
