Luc, I only wanted `/' to be treated equal as `*', not less than `*'
as it is at the moment, but not necessarily more ;-)

,----[ <http://en.wikipedia.org/wiki/Infix_notation> ]
| In infix notation, unlike in prefix or postfix notations,
| parentheses surrounding groups of operands and operators are
| necessary to indicate the intended order in which operations are to
| be performed. *In the absence of parentheses*, certain precedence
| rules determine the order of operations. These are explained in the
| order of operations article.
