+ + Add : The uid() function returns an unique identifier for each dynamic
+ scope. The validate_uid() function can be used to check whether
+ one such identifier is valid (i.e. that the scope it refers to
+ is still alive).
+ + Chg : It is no longer possible on perl 5.6 to call goto() in an
+ uplevel callback to replace the uplevel call. This change was
+ needed in order to ensure consistency between platforms
+ regarding to the following fix just below.
+ + Fix : The uplevel() tests now pass on Windows.
+ Thanks C.H. Kang for bringing this to my attention.
