Changes for version 0.18 - 2011-10-10
- 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.
- Scope::Upper - Act on upper scopes.
