Subject: [PATCH] Launch an UnexpectedError when grammar contains issues
Number of grammar issues were previously output. This was useful for
early language developments but always displaying information is
irrelevant.
Note grammar issues means that the grammar itself is buggy. It is not
related to errors in user scripts.
