Sending print or printLine to many objects will print to stdout.
If you have started Self from the command line on Linux or Mac then
you'll see it in the terminal you started Self from. If you've started
Self on Mac by double-clicking a snapshot, then it will probably
disappear into the ether and you're better off using GetIt.
May I ask which platform and what snapshot you're using?
