Expressions (i.e., messages sends, assignments. . . ) separated by periods are evaluated in sequence. Note that there is no period between a variable definition and the following expression. 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 and not a terminator. Therefore a final period is optional.
