-Warnings are not immediately catastrophic, but you should get rid of

-you may mistake assignment and arithmetic operators (``=`` instead of
-``==``); you may forget the comma that separates properties, etc. For
-all these and many other warnings, Inform has found something which is
-legal but doubtful.
