See patch. More uses of these functions will appear in the name constraints patches. In particular, NestedExpectTagAndGetValueAtEnd seems pretty specialized, but it is also used in for name constraints.

(In reply to [:mmc] Monica Chew (please use needinfo) from comment #3) > Created attachment 8510701 [details] [diff] [review] > Fix dropped return value check ( Thank you for noticing this, and thanks for fixing it. How did you find it? Is somebody building Gecko in a way that causes this type of error (unused assignment) to be found, in a way that isn't found on tryserver and inbound?
