1) Convert weird field name "typ" to the more standard "type". 2) For the NUMBER type, convert the value to an int() or float(). 3) Simplify ``group(kind)`` to the shorter and faster ``group()`` call. 4) Simplify logic go a single if-elif chain to make this easier to extend. 5) Reorder the tests to match the order the tokens are specified. This isn't necessary for correctness but does make the example easier to follow. 6) Move the "column" calculation before the if-elif chain so that users have the option of using this value in error messages.
