Statements and Declarations in Expressions
 ==========================================
 
    A compound statement enclosed in parentheses may appear as an
 expression in GNU C.  This allows you to use loops, switches, and local
 variables within an expression.
 
    Recall that a compound statement is a sequence of statements
 surrounded by braces; in this construct, parentheses go around the
 braces.  For example:
 
      ({ int y = foo (); int z;
         if (y > 0) z = y;
         else z = - y;
         z; })
 
 is a valid (though slightly more complex than necessary) expression for
 the absolute value of `foo ()'.
