uwp does not work from the REPL

This only occurs when in the REPL. Running files works. So it's not really an issue, but I thought it could be mentioned somewhere, probably in the readme.

Thanks for reporting all the issues! Looks we trigger an exception while trying to "stringify" a UWP object (I tested and the basic functionality works in REPL). We'll look into this.
