course, parentheses can be used to express the desired composition.
The Boolean operators \code{and} and \code{or} are so-called
\emph{shortcut} operators: their arguments are evaluated from left to
right, and evaluation stops as soon as the outcome is determined.
E.g., if \code{A} and \code{C} are true but \code{B} is false, \code{A
and B and C} does not evaluate the expression C. In general, the
return value of a shortcut operator, when used as a general value and
not as a Boolean, is the last evaluated argument.
\emph{short-circuit} operators: their arguments are evaluated from
left to right, and evaluation stops as soon as the outcome is
determined. For example, if \code{A} and \code{C} are true but
\code{B} is false, \code{A and B and C} does not evaluate the
expression \code{C}. In general, the return value of a short-circuit
operator, when used as a general value and not as a Boolean, is the
last evaluated argument.
It is possible to assign the result of a comparison or other Boolean
expression to a variable. For example,
