Table column names

Column identifiers can refer to table columns of scalar integral, floating point, boolean, or string type. Mixed-type arithmetic is supported with the exception that names of boolean and string columns must not be used in arithmetic sub-expressions. Names of boolean columns are valid logical sub-expressions, i.e., they do not need to be used in conjunction with the equality operators ==/!= and constants true/false to form valid logical sub-expressions, e.g. BOOLCOL==true is equivalent to BOOLCOL.

Vector columns are not yet supported.
