Operators have a precedence which is currently hardcoded into the parser.

Most operators have the same precedence and are left-associative. This may lead

to non-intuitive behavior; for example the boolean operators "<" and ">"

have a different precedencethat the boolean operators "<=" and ">=".

have a different precedencethan the boolean operators "<=" and ">=".
