Compiler error when not importing anything

[Lukas]

Trying a code snippet that doesn't import anything doesn't work for me on http://online.swiftplayground.run/. When trying just print("lol"), the output is the following:

Using the 4.2 snapshot available now, this doesn't occur anymore. It still does for the release versions 🤔
