Subject: - MFH ?: operator (Marcus)   [DOC] "expr1 ?: expr1" is a shortcut
 for: "expr1 ? expr1 : expr2" as         exists in gcc and discussed some time
 back. Note that this is not         an implementation ifsetor($var, default).
 While ifsetor would not         generate any message for non existing
 variables or array indices         the ternary shortcut does. Also the
 ternary shortcut does a boolean         evaluation rather then checking for
 isset(). That way ther ternary         shortcut can work on any expression
 while ifsetor can only work on         variables. Also to be silent one has
 do do: "@$expr1 ?: $expr2".
