Bad recoveries like the one in Spoofax/168 can lead to large skipped regions. Especially now with keyword highlighting it may not be obvious that at the end of the region there may be a parse error that causes it not to be parsed. Maybe for large, >20 line regions we should mark the entire region as erroneous? Or maybe add a special error marker at the first line of the region, saying something like “region could not be parsed because of subsequent syntax errors (see below)”?
