    Expressions (i.e., message sends, assignments and so on) separated by periods are evaluated in sequence. Note that there is no period between a variable definition (the | box | section) and the following expressions. The value of a sequence is the value of the last expression. The values returned by all the expressions except the last one are ignored. Note that the period is a separator between expressions, and not a terminator. Therefore a final period is optional.

>>> true
