A function with a World Context pin can also be flagged with new metadata CallableWithoutWorldContext which indicates it can be used in any context, even if GetWorld() is not implemented, the called function is responsible for providing a working alternative when World is null
World Centric functions can also be used in classes tagged with the ShowWorldContextPin metadata which indicates the class has a well defined method of supplying the world context that will be connected

This is reported as warning by clang 3.5.0. Arguably not a compiler's call, but it's indeed better to check that condition before calling the function and not inside it.
