We should replace all uses of read with safeRead:

• src/Text/Pandoc/Parsing.hs 739: return (Decimal, read num)

• src/Text/Pandoc/Readers/Docx/Lists.hs 49:getLevel (Div (_, _, kvs) _) = read <$> lookup "level" kvs 56:getNumId (Div (_, _, kvs) _) = read <$> lookup "num-id" kvs 92: read (fromMaybe "1" start) :: Int,

• src/Text/Pandoc/Readers/HTML.hs 323: then read sta

• src/Text/Pandoc/Readers/Odt/StyleReader.hs 581: then read v

• src/Text/Pandoc/Readers/Org/Meta.hs 268: placeholder = try . fmap read $ char '$' *> many1 digit
