The following program, while very weird, should typecheck:

monitor(@com.xkcd.comic()) => @com.smartnews.article()[1 : id];

(note that id is a number for Xkcd)

Instead it does not typecheck because the id of the article shadows the id of Xkcd, which does not make any sense from an operational semantic POV.

(We generate this program because SmartNews has a primitive template for ${count} articles)
