I have been reading in Helen's Firebird book and I found a section
that describes the precedence of comparison operators. Equality
evaluates before inequality, which evaluates before greater than, etc.

It seems to me that comparison operators are simple binary operators
that cannot be strung together into more complex expressions without
the use of logical operators like AND and OR.

Simple curiousity makes me ask if anyone can give me an example of
where comparison operator precedence would make a difference to the
result of an expression. Clearly logical operators do but comparsion
operators don't (or shouldn't).
